I wanted to know at what hp level would it be mandatory to up grade the tranny? What level will stock not work?

This is my thoughts, please advise.
@ 60 hp valve body
@ 100 hp add TC
@ 125+ full rebuild

 

Before upgrading my trans, I was only running edge J/A and on level 5, I would have some transmission slip. After adding on more power making components I had to upgrade the T/C and V/B.
As for the full tranny rebuild it all depends on how much money your willing to spend and how much abuse are you going to inflict on the tranny.

 

talked a shop that installs ATS yesterday.

he said:
ATS stage 4/5 tranny - $5k installed
3yr / 100k mile warranty.

TC & VB installed - 2k
no warranty - either cummins/dodge or ATS.

looks like a signature loan/credit card for an ATS w/warranty is the "right" answer.

 

Make sure that quote is with all billet shafts and while its out maybe add a billet flexplate. Just my .02.

 

@ 50 hp TC
@ 100 hp Performance VB
@ 150+ hp full rebuild


The above would be what I would use (no warranty implicit or explicit).

I hear Goerends has a liftime warranty on their converter and you DON'T have to buy the $4k transmission to get it. Some food for thought.

 

I'm surprised the TC comes before the VB. Does any one else have 2 cents on this?
