I have read several posts lately in which people have had trouble with their 4L60E and it was attributed to the Trans-Go shift kits. I installed one of these kits about 6 months ago and have had no trouble so far. I want to know if there is something I can remove from the shift kit or replace with the stock parts to help prevent the 3-4 clutch problem and the other problems associated with this kit. I really like the 1-2 shift so I don't want to remove the whole kit and revert to stock. I don't want to spend tons of money because my car is pretty much stock and will probably stay that way, but I don't want to worry about my trans going out anytime soon.

Thanks

 

Yes the kit itself shortens the life of the trans. Like many performance parts, they increase performance and cause problems. there is a reason GM didnt bolt a kit like that on from the factory. Reliabilty issues. As far as the Trans-go kit goes its not that agressive of a shift kit. You shouldnt have any imediate problems, but you may experiance trans trouble earlier than normal. the 4L60E isnt exactly a strong trans to begin with, i wouldnt want to add any additional stress to it. But this is just my opinion.

 

How many miles does your Z have on it? Most guys I know with 4L60E's have had their trannies rebuilt at some point already, I have.

 

Once again some one slamming a product that has no knowledge of it.
The Transgo will not shorting the life of the tranny. It will make the shifting part quicker means that there is less time between shifts. When a car shift is where the slipping occurs the faster it shift the less wear that's on the clutches. Do more research on the product before giving out bad advice.

I have had mine in my car for the past two years, and believe me I put this car through living hell. So far the tranny is holding up.

What you don't want to do is to increase line pressure this will shorting the life of the tranny.

 

I am not slamming the product. Like I said, I have had no trouble with it. I have just read some posts lately in which a 15 year transmission rebuilder says that the kit causes premature failure of the 3-4 clutches and/or the 2-4 band. I only have 56,000 miles on the car so I am not too concerned about it, but it just made me think, that's all.

 

Well,i was talked out of the Transgo by my transguy and Ellis who used to post here a lot.
The transgo go does wear out the 2/4 band and 3-4 clutches quicker then any other shift kit.

12secz will chime in when he see's this,and can explain it in detail.

MY lil $800 rebuild has outlasted MANY other $1700+ trannies,and i dont have a transgo,i spray a 150 hit through shifts,and drive the car all over.

 

No Knowledge? I've built Automatic transmissions for almost 15 years. Most of that time was spent in the R&D of performance parts for the 700/4L60E. I'm probably the one that told Russ that the TG kit is JUNK. The fact is it is! Tell me again, Ken, about how little knowledge I have? Enough knowledge to know that every single one of the transmissions I take apart that some underadvised car enthusiast has installed a TG kit in is junk.

Dirk, tell 'em what yours runs WITHOUT a TG kit in it, and how long it's been in there.
This "No Knowledge" professional transmission builder built Dirks trans over 2 years ago. Wanna talk about abuse? 11.2's, on the spray...And it's street driven.

I've had a Trans Go shift kit in my GM truck with a 4L80E with no problems for the last three years. I had no problems installing it and its been trouble free.

 

LOL...Does your truck run in the 11's, or twist over 6000 RPMs.
My point specifically was targetted to the 700/4L60E. I'm not sure about their 4L80E kits. I'm not sure why anyone would need a kit for a 4L80E. I can make them shift so hard the glovebox door will fly open WITHOUT a shift kit. All you need in them is a good pressure regulator valve and sleeve, and drill a few holes...Or, if you want it real abusive leave out the 2nd, 3rd, and 4th checkballs.

Everyone has their opinions but I am NOT a tranny expert, But I do know engines, And cars in general, and their is one rule. ANY and I Mean ANY Performance part shortens the life of the assembly it was put into. Unless you build up the assembly to take a performance part! Once you deviate from the way GM designed it, you are entering forgein land! and your climbing the hill of failures. now that being said, I know people that'll tell you you can bolt nitrous to a completely stock car and it will last forever!! and they have done it, BUT there are exceptions (Actually Luck)!

 

I agree to an extent. The parts I put in my racing transmission help them last longer. Putting a "boxed" shift kit in a performance vehicle is still like putting a Band-Aid on a bullet wound. You're not fixing the whole problem.

No I agree with you My tranny Is Completely Stock, go 91000 HARD Miles on it. I want to do it but I don't believe a torqe converter and a shift kit is gonna be a long term solution. I was thinking about either Dumping the cash to have it Completely rebuilt or go with a T56! I think that you probably build great transmissions, but if you do, I don't believe you do it by bolting on some parts. It starts with some knowledge!

 

If you want to see what I've got in my personal transmission, check out my web site. It's lasted succesfully in my 12 second '93 Z for over 2 years. Click on the "Stats and Specifications" link.

For one I did not say anything to you about knowledge of the tranny so lighting up.
So you rebuild them and they survive congrat's to you anything that you can do to make them survive with these tranny's you must be doing something right. Can't say that for everyone that's working on them.

What in particular that you don't like about the TransGo?

 

Sorry about that. I think I took that too personal. I believe the problems with the TG kit lie in a few areas. The servo mods/band clearance, the accumulatopr mods are ridiculous, and the rest is in the valvebody modifications.
