Took the camro to the track the other day, only to find out that it doesn’t want to shift in to 2nd or 3rd gear at high rpm’s. It shifts fine when just driving in town or the highway however. I know it only a 700r4 but it still doesn’t shift when I let up on the pedal. I recently put in a b&m mega shifter, could that have messed up my shifting? Has anyone else had problems with there 700r4 not shifting and if so what did u do to fix it. The motor is a 305 whit hooker 2055, if that helps any…

 

Well I talked to a mechanic today and this is what he told me. He said that I need new rear end gears, and that my old 2.?? Gears aren’t good very good, and are spinning so fast that they wont allow for the trany to engage in the right gears. He also said I should go with a 3.90 gears or higher in the rear end and that will help my shifting.

Ps I was doing a search and there was alto of talk about adjusting the TV cable. What is a TV cable and do I need to adjust it?

 

...you're mechanic just feed you a line of bull and is trying to bend you over. You're rear gears may be worn from age/mileage, but that has nothing to do with the trans shifting or not.
- two things: 1st being the TV cable adjustment, 2nd the trans governor.
You need to check that the cable is adjusted properly, then you need to match the governor weight to the rpm band of you motor.

 

Well first off it wasn’t my mechanic, and I wasn’t going to get the gears put in by him so why would he fill me full of bull-****? It was actually one of the college professors at my college that teaches automotive classes, so I figure that gives him some credibility, and he use to be very big into drag racing. Anyway like I said b4 what the HE*L is a TV cable????? Also could you explain a little more about how to get the governor weight set at the right rpm band of my motor? These are probably common questions about the 700r4 so thank u so much for resonding.

 

Ok well took the car to O-Reilly tonight and they readjusted my TV cable. It dint seem to help very much. Told them about the gear thing and they were like wtf who told you that, just like you did shagwell, so I’m guessing that’s not the problem. They pretty much suggested my tranny is on its way out, and that a th350 turbo is the way I should go. Basically now after they readjusted the TV cable the car will shift weird. For example it will go up to 4000 rps and then back down to 3200 rpms to shift. The car feels slow now, and I don’t know what to do. Should I fix the trany, or should I get the th350 and rebuild it b4 I put it in the car, and if I do that will it work with my b&M meagashifter? What mods should I do to the new tranny? Idk wut do u guy think?

 

The turbo 350 has a less steep (higher ratio) first gear. It also has no overdrive. If you feel that the 350 is better for your needs, you should swap it. If you prefer the 3.06 first gear ratio and like the overdrive, you should have a pro trans shop rebuild your 700r4.

 

whats the average cost to have a tranny rebuilt? My car is geting to the point where it is only used for shows and at the drag strip tho's are my so called neededs.

 

In my part of the country, a 700r4 runs about $1000 for a stock(quality) rebuild with a new stock remanufactured converter. This assumes you carry in the trans and do the removal and install yourself. You can spend more or less.

 

Haha, the mechanic bit is hilarious!

Your tranny doesnt care what speed your doing or what gears are in the back, all it knows is 'o look were goin WOT, spinning up to 5000RPM, time to grab another gear!'


So is your motor a 305 or 350? I see 305 in the post and 350 in your specs...

Either way it seems you have a pretty mild motor so you dont need to go hog wild on a tranny build. but you dont want to just throw in a stock tranny either if you plan on going to the strip!

 

So this idiot that told you that is a automotive technology professor? I feel sorry for the students he is teaching. This idiot obviously does`nt know his *ss from a hole in the ground. I have known alot of these higher education types that thought just because they went on to college they knew it all when in reality they guy with hands on exp. knew volumes more on the subject. This professor sounds like a first class idiot.

 

Well when I bought the car I was told it was a 350, but later found out how to read the block number, and found out its only a 305. If I’m going to rebuild the tranny I’m going to do it right and put the best tranny in that I wont ever have to change, and will be solid as a rock 4 at lest my life time.

 

...if it's only show and race, go T350 manual valve body and re-gear the rear. If you want to cruise or street much, freshen the 700 and go on.

...and if this auto professor was very into drag racing(with an auto trans) then he should have been running a manual valvebody car that is in what ever gear you put it in, when ever you put it there. - one way or the other, rear-gearing doesn't effect whether or not the trans can shift.

 

so where is a good place to start looking for a 350 tranny?

 

good places to start.. um. classifieds mostly.. I have a stock TH-350 out of an 80 camaro that is just collecting dust. suppose i will sell it one day lol. Another thing about that auto professor.. if you have a 2.78 gears then it is turning 2.78 times for every rotation of the driveshaft if i remember. if you go to like a 3.73 or 4.11 then they are actually spinning faster (IE the gear number is the first part of a ratio so 2.73 = 2.73:1 and the 4.11:1 and so on. Also. Just curious.. are you running a stock quadra jet carb on there? (i ask that alot when it comes to the 700r4)

 

problem : worn 3-4 clutch pack.

 

And i can fix that HOW????

and yes it just the stock carb...

 

you fix a worn 3-4 clutch by rebuilding the thing.. I mean since you have the thing appart you might as well replace all of the clutches and such and beef them up a little bit. and replace the servo, TV valve. and the other assorted improvements lol. I do not know offhand what all tools are required to do it at the moment.. but if you are good with diagrams it is not super hard to do.
