I have an 85 700-R in my Z which I just put a shift kit in, the 1-2 shifts are very hard but the 2-3 shifts are a little soft yet it took all the punishment I could put out with my 305(LG4 + 1.6rrs+headers+edelbrock performer+3"flowmaster+3"K&N+Accel coil, wires) Now I am in the process of building a 350 (rebuilt heads= 3 angle valve job+bowl blending+higher compression(8.75:1)+ compcam(218*/222*--.490"/.500")+MSD6AL+mods above from 305,2.93 rear gears.) do you think the 700 will hold?

85 isn't really a good vintage 700r4. 88 and up is better, but still I notice if you put some serious heat in front of them it doesn't take long for it to start slipping (more like neutral lag time) between the 2-3 shift. The more you beat them the more lag time gets permanently added on. If I knew what this prob is I have 3 88 cores with about 30,000 miles on each with about a 5 second lag between 2-3 I would rebuild them. My buddy rebuilt his (clutches steels ect) but it doesn't fix this prob and I don't want to waste $200 and my in-out time to find this out.

All I know is that if you start thinking about messing with TV cable settings other than self-adjust the babys not long for this world

my boss rebuilt his chevelle with a 450 big block and has a 700r4 behind it

 

Thanks for the info JoelOl75, but does anyone have a rating on what the approximate number is? I have read about 300-320hp is the max that the trany's can hold but am not sure. I do not know if the combination(in my first topic) I am building will destroy this thing. If anyone has some insite please tell me. Thank you.

he is estimating to have ABOUT 400hp in the chevelle he is going to dyno it when it comes out for the summer but all he done was put corvette servos in the tranny and he hasnt had any problems and he drives pretty hard all the time

I put a shift kit in it and have a tranny cooler in front of the rad and a local shop told me that would do wonders but what are these servos all about, where do they go in, how hard are they to install,how much do they cost and are they worth it. mine shifts hard 1-2 but not 2-3, I think i installed the shift kit wrong but i triple checked everything, please help

I have an 83 305 700R4.. it has 87,000 miles on it and i went to change the tranny fluid and there were peices of bushing in the pan! Sp i changed the fluid and am going to drive it till it blows then put a later model 700R4 88 up i believe. the earlier ones were weak.

 

Hello. My name is F.C. I'm owner of Racing Transmissions by the Tranny Doctor, Reno Nv. By all means I'M not trying to be a smart a-- but the 700R4 is my specialty, I know them like the back of my hand. I am running two in my owe vehicles which one is a 86 Z28 with over 450 HP and I have no problems WHAT SO EVER and I beat the crap out of it. The 700R4 trans built the right way with quality parts is the best trans ever build (along with the th400) so my question is why does anyone say it's a bad unit? Fact is they are all book readers. I sell a Street/Strip 700R4 with every goodie known to man installed with a deep dish pan plus cooler for 899.00 with a unconditional warranty that with a GOOD converter will hold up to 750 HP. An other thing the early transmission is a GOOD transmision it just needs minor help. Again I'm not trying to be a smart a-- but when I hear quotes like my buddy builds his 700R4 with steel clutches and I had 13 clutches installed in my 3/4 pack, enough is enough, they don't make steel clutches. If you own a 700R4, you have the best transmission ever built as long as it is done right and you must have a good convertewr to go with the trans. F.C.

 

Tranny doctor....

Maybe you can help me then. I don't mind rebuilding my own trans, but what could be possible causes of the 1/2 shift point increasing itself from 4500 rpm up to 5800 rpm? This might be linked to the 'neutral' lag time starting in the shifts. The trans is only 8 mos. old and has less than 10,000 miles on it. Its a TCI Streetfighter with a Saturday night special TC.

Any input would be appc'd. Thanx

 

or you could buy my th350.as you all know they are alot more reliable that the older 700's. this one come out of a 83 camaro with a v-8.the car originally had a 700,but the guy got a 350,and took it and a adapter kit to a trans shop,and had the rebuild the trans+put the adapter kit+shift kit put in.it has about 150 miles on it since rebuild(parted the car...he wrecked it on the front,still was driveable,i made sure the trans was ok.)i was going to use the trans for myself,but i got another camaro with a 5-speed in it and i like banging gears better.i have the trans,converter,driveshaft,and x-member.asking $375 o.b.o.,or trade for wc t-5.

Joel, I know what you're talking about, it happened in my 86 and I bought my 91 with the slippy trans shift between 2-3. I'm almost sure that the reason is for cheap trans fluid, no magnet to pick up metal, and poor trans fluid cooling. You get what you pay for so to speak. Get a trans cooler or a trans fluid temp sensor & guage to check that the fuild isn't boiling and destroying the clutches. The reason for high trans temp is usually a kinked metal line up near the stock trans cooler or the torque converter. A cheap torque converter will heat up the trans real bad. Hope this helps.

Joel. This F.C. This is a really, really an easy question. You have a TCI unit Sorry. At one time TCI made a good product but not any longer. 50% of the time there product works and 50% of the time they don't work. I have worked on TCI units many of times and when a person pays 1300.00 for a unit don't you think the unit should be shimmed by using selectives instead of using 3 pump gaskets. We just built a unit for a customer that has a TCI which took a dump and he sent it back to TCI and it took 4 months to get it back, he put it in and after 3 runs it took a dump again, he sent it back and has not gotten it back after 6 months so he did business with us. Any time you have late shifting in a 700R4 trans it can be either TV binding or not adjusted right or TV cable pulled itself out of adjustment, stuck pressure reg valve or TV boost valve or valve body or seperator plate. My guess is bad TCI transmission.

 

Im no tranny doctor, however, my experience with the 700 has been ****ty until I put the corvette sevo in. I had a flare on the 2-3 **** just like all of you guys and I talked to a race mechanic friend of mine.......he said hes seen it a thousand times - all you need is the corvette servo and the 2-3 flare is gone! I put it in and low and behold, the trans shifts great. This same guy has 10 second el camino which he ran a 700r4 in that he built, the engine dynoed something like 800HP. I'd say with a good trans kit, and the vette servo you should be in good shape.

Well. I have a B&M racing cooler and there's a magnet in the pan... I never overheated. It might be the fluid (cheap). I noticed it does it more when cold but shifts fine (harder) when driven 10-15 miles. I might actually be breaking traction (my tires do very silent burnouts). What about putting Ford type F in there. Some say do it.. Others say it'll destoy it. I have to change my filter and clean the magnet anyway. Hope I don't see anything too scary

Sorry mike... 4.10:1 rear gears demand the O.D. A Th350 will kill me
