TH350,TH400 or 700R4

[shaved67]

I have a 87 camaro with around 320 to the wheels i have learned about the 700r4 or 4l60 the hard way. If you are going to have one built get one from a junk yard out of any 90-92 vehicle have whoever builds it for you put kolene steels and raybestos clutches in it and make sure that the governor is matched up to your desired shift points and vehicle weight.
the biggest problem with this trans is quick high revving engines.
this starves the clutches and steels for fluid and burns them up.
t.v. cable adjustment is vital and supposedly tci's new constant pressure valve body helps maintain fluid pressure.
I had mine built by a local one man show who builds pro-mod trannys and he guaranteed it to 600 fly wheel hp. I tried ati's 700r4 it lasted less than a week and never shifted properly tci's are hit and miss.go with art carr,raptor or someone like that it should cost you around 2000 for the build and anywhere from 300-600 for the used trans. all you have to do for it to hold wot in fourth is to have the tv valve replaced and it will hold 4th to about 75% throttle which is pretty fast. I have 9000 MI on this tranny w/o any issues and I don't baby it too much. An aux cooler is a must. and if you run a lock up converter it has to be locked up in o.d. or it will blow up I know


hope this helps
