I have a couple of questions for Factory Tech or other trans guy
1:I already have a Super chip that firmed up my shifts 2-3 shift is Bam! when at WOT. The 1-2 shift could still be a little firmer if I do the accumulator body mod will the combo of the higher line press from the chip program and the mods to the accumulator body be too much?
2: could I go in and just beef up the 1-2 shift (with the spring from the 4R100 shift kit) and leave the other shift springs alone and be ok?
any help/advice would be Great. Thanks

 

you really need to talk to gregg evans about having your chip control the shifts.
in laymans terms _.. NOT GOOD!

your tranny will NOT last.

I have his FT VB and STOCK shifting on the chip. best or both worlds

 

Ive heard good and bad about the subject. I have Greggs 2CR race valvebody , 2800 stall and JDMs chip. It is a necksnapper. Not for the faint hearted. I like it because of the loud barking tire chirps.. But I will tell you that I have had many accidents with coffee etc etc spillage all over my interior and back window due to these extremely hard shifts...

 

promodlightning, it doesn't sound like you should go driving If you have a runny nose....real spotty rear window tint!

 

I can tune you a valve body for just the 1-2 shift, but it'll be better if you have your tuner reset the tranny to stock and let me do it right. There are pump issues with shortening hte shift timing with software, and maybe some possible lube problems, and ...well, it's just better not to do it. An accumulator can be tuned to however you want it, I can tune it to within 3ms by changing the casting and the 321/310 spring and valve, and it doesn't hurt anything to do that.
