stuntstere Posted November 27, 2011 Report Share Posted November 27, 2011 The tbss was the first vehicle to get the 4l70e trans from gm which indeed has some significant issues.. the clutchs burn and the bands break. An afftermarket preformance trans would be a better bet but pricer. Some people convert to the 4l80/90 trans itself and that holds up a lot better than the stock 4l70.. what gm tranny doesnt have issues lol LOL yeah all GM trannys have issues. The 4T65 and 4L80 probably have the least problems from my experiance of what comes into the shop. But then again I work in a Caddy shop where most of the trans issues that come in are 4T80s out of the devilles/seville with TCC lock up solenoid issues with burnt up torque converters.

1988JimmyRE Posted November 27, 2011 Report Share Posted November 27, 2011 the only trans that i use for my race cars is a thm-350 but you will want over drive of course, my trans cost me 375.. you could get a 700r4 for about 1500 that'll handle whatever you throw at it Quote BUILD LOG-->1988 S15 Jimmy V8 4x4 2 15" RE Audio<--BUILD LOG Link to comment Share on other sites More sharing options...

Yeah those have bad issues with reaction sunshells breaking or the one way rollers lets go in them. If you can do your own trans work, there is a ton of money to be saved. 4L60 to 4L80 transmissions are pretty simple to go through. A clean work area, a compotent manual, and good lights I believe most people with good mechanical knowledge could go through one and fix them. Personally I think the worst part is installing and sizing teflon seals if their needed. Quote Link to comment Share on other sites More sharing options...

Buddy has one on a built LS3 02 camaro spraying a progressive 2 stage 500 shot on it. Handles everything he throws at it. And personal opinion I believe the turbo 350 is no better than the 4L60 in comparision to power handling and strucural design, but are cost effetive transmissions to use though in Quote Link to comment Share on other sites More sharing options...
