Has anyone else had a problem with the 4r100 2nd gear?? Mine keeps breaking and the shop can't tell me why

 

more info

 

do you have a chip with torque reduction turned off?

 

I have a diablo chip but im not sure about the torque reduction? It drives fine but when i punch it, it hits second and goes into a neutral state but i will have my guy reprogram my chip.

 

For transmission longevity you want torque reduction left on and the line pressure left alone. Basically you don't want that chip to change anything with the transmission except maybe shift points. You should try to get a hold of gregg evans and he might be able to help you out, but like buckstop said you'll need to provide more info. Year of truck, mods, how long it's been modded, how many times the tranny's gone out, routine maintenance performed, how many miles on the truck, etc.

 

Second gear is the weak spot in the 4R100, you can upgrade the sprag ($65, I have them) and the Intermediate clutch plates (I have Blue Plates for $24 Each, 3 required)

Sounds to me like you're breaking sprags, but you're plates are prolly toased too.

Hope this helps,

What kind of hours am i looking at for labor for the install??

 

Hey, where in CT are you located and who keeps doing your tranny>??? We have 3 shops in CT and I am sure we can get your truck going good. Let me know if I can help in anyway. -Mat-

 

I live in Meriden but i have the tranny under warrenty at the dealership i bought it from cause this is the second time in 6 months that my tranny went.
Do you know someone who can reprogram my chip??
The shop i have do my work is Cody Mac motorsports but I really want to go somewhere different.

 

When it's out of warranty, call me and I'll build you one that to blow you'd have bolt to a GE 90 Turbofanjet, and you'll get another 2 year warranty on it.
