if you are gonna get a built Trans the only one you should get is a CPT and forget about that B&M, Frank has these cars with 4L60E's running 11.00 for 3 years on the bottle with no problem! He is the best 4L60E trans builder out there.

check out the link above for info.

 

Definetly cheaper than I thought it would be for a built trans. Will take that into consideration...do the M6 cars have issues similar to this? I know the T-56's are damn strong and can take abuse.

 

I am curious as to why you would do that? Isn't the 700r4 just the 4l60e with out the e, or electric control. Mechanical they are the same right? So they should have the same torque capacity, if they are both built using the same parts. I would like to know becasue I still have the blown 700r4 out of the 91rs. I just figured when the trans. went, then I would just stay with the 4l60e, and not rebuild the 700r4 as a spare trans in the mean time.

 

A window switch set at say 2-300 rpms above peak power and then have the car shifts 200 rpms after that. I.E. The car makes peak power at 5200 on juice. Set the window switch to 5500 then shift points at 5700 or 5800. That will help the trans out ALOT!! I hated busting up transmissions. It got more expensive everytime because I would grenade all kinds of crap. Took out the converter and the front pump once. LOL

 

So can running a window swithc help me avoid the issue of blowing the trans up on the bottle? I know it helps but could it be the difference between longevity and replacement?

 

It will make the trans last longer than without is all anyone can say. It;s never a guarantee. You could still damage it. Make sure you get a trans cooler and shift kit for the car. Try to keep it from lagging between the gears and cool.

 

you mentioned a shift kit^^^i may sound stupid but dont all a4's have one?i have a button that says trans perform i push it and it shift hard and fast.oh and my car is a 94 formula

 

That button just increases line pressure for a firmer shift, From what I have heard from more than 1 builder is that the transgo kit's cause damage to the 4L60e's so you might wanna research it abit b4 you go ahead with it.

 

so should i get a shift kit or leave it alone,should i even use this button? i already lost the trans once and always woundered if it was because of me using the trans button to much. i dont want to lose another before i can get a back up trans.

 

I am not a Tranny pro but for an educated answer PM 12SCNDZ his name is Frank and he is also the owner and cheif builder of CPT he can better explain why and how it damages the trans,

don't be shy he is a really nice guy and will do everything he can to help you out! Tell him I sent you.

From what I have always been told is that firmer shifts improve trans life because it is easier on it when the lines are full of pressure than when it shifts soft. I dont see how the performance button would hurt it especially since GM put it there and was meant to be used. Does B&M make a shift kit or who makes a good quality one?

 

sounds cool, they are just 5 minutes from where i buy all my fireworks. guess i know what im doing next month.

 

I realy haven't data to support this, maybe you are right, that was a recomendation of guys that have good experience using 700 on older and stronger cars.

 

Not sure what in the heck performance button you're talking about. GM never put any transmission performance button in an F-body to my knowledge. I know there is a device from B&M I believe that sounds like what you are talking about.

Regarding shifts kits, TransGo is going to be the most popular. I'm running one with a Vigilante 3200. On spray, I have the window switch set to 6000 and shift points at 6200 (car peaks at 6200 with LT4 hotcam). No problems last year at all on an otherwise stock transmission.

My advice, if you can't afford to replace/rebuild anything, then stay away from power adders and keep the car stock.

not to hijack the thread...but what model shift kit are you using?
