Trying to decide if this is a product I should try.My car shifts into fourth early so much that I drive around town in third gear.I never shift it into OD untill i hit about 70 mph on the interstate cause it seems like it has a hard time deciding if it wants to be in 3rd or 4th,shifting back and fourth if I leave it in OD around town.My trans seems to be in good shape besides that problem and a sometimes sluggish 1-2 upshift at part throttle and sometimes at WOT.My car shifts into overdrive between 40 and 55,depending on how much throtle I`m giving it.I guess it`s worth a try for the price and of I don`t like it it looks easy to install and remove.I do plan on going through my trans soon.

Hey Shady, the spring will definitely firm up your 1-2 shift. As far as it shuttling back and forth (i.e. 3-4,3-4), mine used to do that too, and it drove me nuts. I used a different item to cure that problem. I installed the B&M 3/4 shift sleeve. This changes the 4-3 downshift to 2/3 throttle instead of the factory 1/2 throttle position. The sleeve I'm referring to is the TV plunger sleeve. You have to drop the fluid pan to install it, but it's a piece of cake to put in. I did mine when it was due for a fluid/filter change. Personally, it's probably the only B&M part I would consider using in a 700r4. It works great though and it hasn't shuttled back and forth since installing it. If you want 4th gear capability at WOT, you could opt for the Vette shift sleeve instead of the B&M one. PATC Raptor corp. sells the Vette sleeve for about $40. So the sleeve will fix the shuttling problem. The other problem I had was when I changed to better rearend gears, it'd shift into 4th too early (about 35 mph), and the spring took care of that. When I don't have the spring installed, I have to leave it in Drive til I reach 45 mph, otherwise you can feel the motor lugging because it goes into 4th too early.

I used the Superior/Fairbanks 3/4 TV sleeve for WOT 3/4, and I believe this sleeve bumped the 3/4 shift point up substanitally. I have a 1986 700R4 with just a Superior $39 shift kit in it, and the corvette servo/accumulators, and the Superior 3/4 sleeve, and I can not get the trans to shift into 4th below 50 mph. And it only goes in at 50 mph at like 1/16th throttle. If you are in the gas more than barely cruising it won't shift into 4th until well above 50 mph. I actually prefer that it shift into 4th sooner than it does but I can't change it at this point. Most people would probably love the way my trans is set up

Thanks for the info.I`ve searched the boards a while back and couldnt find an answer for that.Thanks again

i bought the vette server and the boost valve too but i cant figure out how to get the plate off to get to the servo and i don't know where the valve goes can some one tell me where or better yet send some pics?

camaro91boy

the 3- 4 shifting up and down is a problem with 85 and earlier tranys so ive been told you can either get an up grade or find a 86 and newer trans. i had a 84 trany out of a camaro in mine and my car ate it up it kept shifting up and down and when i was racing in the curvy hills it blew out the pump and then burnt out all of the clutches so either be careful and dont hotrod it alot or get a newer tranny i now have a 92 trany out of ws6 firebird and it looks physically beefier than the 84 when side by side but it shifts so smooth that i cant feel it so im changing a few parts. also can anyone supply a fool proof way of setting the shifter indicater in a camaro the cable from the shifter to the tranny is off and dosen't set in gear just right.

I orederd my spring a few days ago.Was off work today due to rain and put it on,Took about 3 seconds.All I can say is I wish more products were as inexpensive,easy to install and showed as noticeable a difference.I dont normally drive my car in rain or wet road conditions but I couldnt resist in a break in the rain.My sluggish 1-2 shift is a thing of the past now and it doesnt shift into OD untill my speedo is at 60.(I`m 99.9% sure my speedo is off,got a ticket doing 79 in a 65 with my cruise set on 70)So that sounds bout right.I was a little worried after I pulled out of my driveway,I kept waiting for it to shift and I didnt think it was going to.At 3 grand pow shifted like a mother.I am happy with it and the cool thing about it is if you dont like it or get tired of it it`s easy to remove.My car shifts more like I want it to.I used to shift it manualy to get those kinds of shifts when I was showing off or playing around.Just hope the trans holds up with it.You can barely be in the throttle on the highway if you want it to shift into OD.I kinda wish it shifted a little sooner than 3 grand on the 2-3 shift but I still love it.

Hey Shady, if you loosen your tv cable a click or two, it should drop the 1-2 shift point a bit. Mine did the same thing until I fine tuned the adjustment.

Destructimus

I bought mine from transmichigan.com. Cost me like $16 but I accidentally put the order in twice. Got an e-mail asking if I needed two and they fixed the problem for me. Most places wouldn't do that so I thought it was worth something.

Yeah,I can get the 1-2 shift down where I like the shift but it`s not as hard as a shift as I want it to be.Oh well,cant have it all.It seems almost just like the stock shift just a lil quicker ,not so sluggish.The 2-3 shift doesnt seem to want to change that much.Then when the 1-2 shift is where I like it it shifts into OD sooner than I want it to.I`m gonna keep foolin round with it see what I can come up with.Thanks

btcamaro

hey 327 I am not sure but I have heard that shift kit comes with a stiffer 4th clutch spring and that in order to bring your shift back down you will need to remove the spring and go back to the original. heard that from some trans builders here.

I've had one of these little buggers on my IROC for 7 years/65k miles now.

sorry to dig up an old thread but while i was searching for info about the transgo shift kit i came across this thread here. seems like this spring is exactly what im looking for in terms of firming up my shifts and raising the shift points. that seems to be the trend, correct me if im wrong? from what i can tel it is installed where pictured by fast 355's pics right? thanks for the help

Just found this thread, and had a quick question, would this do the same for my car, stock L03 with 700R4? I just ordered the corvette servo and was searching for how to install it once i get my car out of storage. Its a daily driver but just for around town, not a trip taker by any means. Since Iv found this forum im excited to get it out and make it fun to drive again. Bought it 7 or 8 yrs ago and has kinda lost its fun without doing any mods to it. But back to the subject, will this make my shifts super firm like everybody else is saying or is it only worthwile if i have gears and other goodies?

it will change the shift points a bit. It real purpose is to correct line pressure issues after you swap rear gears. I originally had 2:73's in the rear and after i swapped to 3:73's, the trans shifter way too soon because of the extra rpms. The spring delays the shift that the detent cable causes and helps correct the early shifting.

For 15 bux, i wont hurt to give it a try.

Thanks for the info, trans stuff confuses the #%*! out of me, so I just dont touch it, but this forum has helped me figure out stuff and give me ideas, wish i would have found it WAYYY sooner.

I like shagwell's post.
You wouldn't want to do this for customers because of late shift complaints, as it pulls the t.v. cable a little more to move the arm towards the plunger. If it is moving the plunger in at all it isn't what you would want to do. The correct way to adjust the t.v. system is with the pan off. The arm should just be meeting the plunger at idle with six lines showing on the plunger valve. at wot the plunger should be buried. WITH A PRESSURE GAUGE IF USING THIS SPRING IF YOU DISCONNECT THE CABLE AND THE PRESSURE DROPS MORE THAN 3-5 LBS IT THOULDN'T BE USED. I don't like the spring, it is a good gimmic and probably made lots of money for the seller, but know better on my own ride so I wouldn't use it for my customers I'd fix the geometry in the first place. This can be done by altering the connection point from the centerline of the throttle shaft. not a spring that pulls the cable prematurely and collapses at full throttle. gimmic busted!

Does anyone have a rough figure on the effects on your fuel mileage? I have read through the thread but didn't see any numbers of how much was lost.

Atilla the Fun

Some of you really surprise me. My first 700R-4 came out of a mid-80s caprice LG4, and with only a new spring in the 1-2 accumulator, the Painless Wiring lockup kit, and shortening the driveshaft 2", went into my '78 Camaro 350, all stock, with 3.08:1 axle.
When driving, it would go into OD as low as 30 mph, doing 830 rpm, and it was really nice. Never since have I been able to get any other 700R-4 to let me do less than 35 in OD. Maddening. I drove a '95 Eclipse, non-turbo, that also turned 830 rpm @ 30 mph, in fifth, also not lugging.
Now, I loved my '95 Z28 with Hypertech programmer spinning to 6200 rpm in first, so I'm not prejudiced against twisting an engine up tight, but there's no good reason to be stuck in third when you could be in fourth.
To be fair, I had another camaro that seemed to be lugging doing 2100 @ 65 in fourth, it was an L69 with 1.94" intake valves, a performer intake, and a cam, but a bit of tuning, just carburetor and distributor adjustments, was all it took to resolve. NOT more rpm.

As I understand it, there is only one correct position for the TV cable. You are not supposed to adjust it to alter shift points or hardness/softness of shifts. It is supposed to be set so that it is fully out at WOT, that's it! Any adjustments to shift points should be made with governor springs and weights, and the softness/harness/quickness by modifications to servos and valvebody bits and pieces.

This thing maybe OK, but you have to be careful with the line pressure, if you don't have enough you will burn stuff.

TreeFiddy

Problem for many is that once set up this, the correct way, you end up with sloppy short 'stacked' shifts. This is often caused by the tv spring in the trans being worn out, and compressed too short over time, leading to the idle position of the tv cable being too far into the tranny.

http://www.tvmadeez.com/article/part3.php

Sofa summed it up many posts ago - this new spring works like a bandaid for THAT condition - 'short spring syndrome'. If you don't have that condition, this new spring will cause really harsh shifts that occur way too late, as some guys have reported. Of course the correct fix is to renew the tv spring, and make sure the throttle link geometry is correct.

I have this condition to a small degree, and have only just realised this simple trick existed - must give it a go!

TreeFiddy

Some further research, looks like they come in a 5-pack now, for fine-tuning maybe? Can't tell if the springs are different or not.

OK, I see, good point. I just see a lot of people trying to alter the trans characteristics by fiddling with the TV cable, which I think leads to more problems down the track.

^^+1 This definitely looks like a product that is a bandaid fix for people who don't want to go through the valve body of their high mileage 700R4 to fix what is really wrong with it, or who don't want to troubleshoot throttle valve geometry problems. There is a lot of flexibility in changing shift timing through the TV and throttle valve circuits in the valve body, and there are definitely parts in the valve body that wear and require correction/replacement over time. Now that I have been rebuilding my own 700Rs I have found very few valve bodies even from 'good working' high mileage trans that did not have some worn/sloppy/stuck parts inside the valve body that needed to be repaired.

... and yet they are adjustable from the factory. Like sofa said in almost every single one of his posts, it offsets "short spring syndrome". The spring will not hurt anything. I have been running that spring in conjunction with loosening the the detent cable by just one click for years, not one problem. Any system that provides for harder and higher shift points will shorten the life of any stock 700R4, not just this spring. But hey, that is hot rodding.

327_TPI_77_Maro

If you know you have short spring syndrome, why not drop the valve body and put a Superior or Transgo TV spring and plunger kit in it...it takes a few hours to have out and back in.

Cosmik Debris

Yeah, that sums it up I guess.
