1995 z28 with trans go shift kit 2800 vigilantie ,deep pan I have over 3000 miles on converter and shift kit. If I take off from a stop with any thing more than half throttle it wont shift it to second it just tags the rev limmiter. It will do the same thing if I down shift to first then try to engage second. If I just baby it off the line it will shift in to second, but it is so soft I cant even feel it any more. It used to shift hard into second. the trans fluid was changed 500 miles before This problem was noticed and within that 500 miles it got dark. It doesnt stink its not black but it doesnt look good. Is this the 2 to 4 band or something else? Im getting no service engine light, so I dont think it is the tps sensor.

 

...Another victim of a Trans-Go shift kit. I'd say your 2-4 band in wasted. I keep telling you guys that these kits tear stuff up.

I'm a bit confused here, you said that the installation of the transgo,"tears stuff up". You say that the 2-4 band is "wasted", yet you offer not one reason why. Are you just stating your opinion?? Frank why does the installation of the Transgo HD2 kit tear stuff up??? What are your thoughts ....I'd like to know for my benifit, as I've installed over 300 of these kits and have never had a problem. .....Help me to understand??...Dave

 

No, Dave...It's not OPINION, it's fact. Most all good professional transmission builders stopped using Trans-Go stuff a long time ago. The gold steel ring they provide to "take up band clearance" is absurd, and will cook the band on every occassion. This isn't opinion...I've never taken one apart with one in it that the band wasn't cooked...No matter who built it. The Tg build kit gives you HEAVIER load release springs for the 3-4 clutches!? Anyone who knows anything about racing 700/4L60E's knows not to install ANY springs in the 3-4's...Let alone heavier ones. TG vacuum modulator? Come on, these things toast transmissions better than anything.
Trans-Go is a complete joke. Fortunately for their sake, they got alot of people who don't really uinderstand automatic transmissions to buy into their bad ideas.

I've got to ask why a professional would think about spending so much money on a TG kit. The only reason they would do so would be because they don't understand how a transmission actually operates and what they need to make them shift correctly, and live long. The TG kit misses the boat on what REALLY needs to be done to make these things work, anyway. Don't any other builders know this?

I've got enough customers on this board who are more than satisfied with the transmissions I build (without TG kits)...Simply because I KNOW what tears them up, and I understand enough about them to build them correctly.

so it's the gold steel ring that burns up the 2-4 band? What is centrifugal apply? And how does it relate to the 3-4 clutch? And last but not least how do you retain the 3-4 piston without springs?

You stated that the vacuum mod kits "toasts transmissions better than anything" but you haven't said Why....I think that’s the part I really don't understand, what is it about the Vac. mod kit that "Toasts" transmissions? Is it the modulator, bushing/valve, pin length?? We had one that the valve stuck in but it was in the high line side...so we didn't burn it up ....hit like crazy tho. I'm jus curious.... you know like most builders thats what landed all of us into this profession.

You asked,
"I've got to ask why a professional would think about spending so much money on a TG kit."
Simply put? They work well, and address most of the issues as they pertain to the inadequate line rise in these units. The quality of the kits far surpasses other manufactures and they are widely available. Along with the vac. mod kit, now you can bypass the computer for dependable, consistent, faster, higher, none electrical, failsafe, and max line on demand to mention a few benefits of the combo.

So let me understand....because I use transgo products I don't understand automatic transmissions? Is that what you are implying?

Frank I'm not attacking you; I'm seeking information from a technical board. I believe what makes a good builder is their ability to keep an open mind and is always seeking a better way. I haven't had the Experiences you've had with transgo products and are simply trying to understand your blanket condemnation of transgo and the builders who use the product. Hope this helps...Dave

 

Dave,
The only point I'm trying to make is this. If it's available for a 700/4L60E I've tried it. I know what works and what doesn't. If I know for a fact that some things don't work, I'm trying to get all the other board members to avoid them.
You've asked me in 2 other threads about the problems with TG kits, and I've explained many problems from the kits.
Do you know the difference between load release springs and piston return springs? Obviously you have to put a piston return spring in the 3-4's. Nobody who knows what their doing reuses load release springs, unless they want repeated 3-4 problems. I've never seen any signs of Centrifical 3-4 clutch lock-up by not installing them...Then again, I do try to keep crossleaks to a minimum.

We use Transgo products along with others in the different transmissions we do. We have had tremendous success with these products and a few failures. Normally we’ll find most of these failures, were after all is said and done; builder in nature and not product. This goes for the vast majority of the products we use. I unlike you have had great success and would encourage others on the board to use these products. I don’t think installing a gold washer ruined this transmission. Without seeing this transmission, and with the information given, no one can determine what caused the failure.

I have asked you about transgo products in the past and like this last post you managed to skip the question and go on. When you make blanket statements about others, products, and your competitors, I think you should be ready to defend your position with something besides conjecture.

Frank, you ask if I know the difference between load release springs, and piston return springs. My understanding is that load release springs were added to prevent centrifugal apply while the piston return springs were installed to return the apply piston. While it’s an accepted practice to omit theses “load springs” on a rebuild, there are certain benefits by reusing these springs. Those benefits include among other things, fuel economy, cooler clutch temps, longer clutch wear.
You go on to state” Nobody who knows what their doing reuses load release springs, unless they want repeated 3-4 problems”.
Do you mean what you said? And again I’ll ask; why do clutch pacs that use these springs burn? What about the springs causes the clutch to burn?
Cross leaks are a big problem with this unit, that is easily addressed, but cross leak apply shouldn’t be confused with centrifugal apply. Again an easy fix. I think there are more builders out there that confuse the two and don’t really know the difference, than you and I will ever know.
It’s nice that we can have a technical forum where we can share ideas that not only benefits us, but the board members. Hope this helps….. Dave
