Shift Kit or will tuning be enough?

[JoeliusZ28]

Im due for a transmission fluid change so i was thinking about doing the shift kit while im in there. However my buddy has a laptop with HP Tuners that im thinking about buying a lisence for. Would i be able to mess with the firmness in the tune? I know for a fact the torque management needs to go... My old 700r4 shifted so much smoother without that. The way my truck shifts right now is like it lets off before it shifts (enough that you hear a clunk sometimes) and then it shifts moderately firm. ... and i know this is exactly how torque management works.


I want firm and progressive shifts that put me back in the seat a little, but i do NOT want anything harsh. If it chirped 2nd WOT without shaking the truck id be very happy. I already have the corvette servo, and i like what that did but it still needs more help. Id rather not mess with the line pressure because ive heard that hurts your gas mileage. Weve never used HPTuners with an automatic so im not sure what we can do with it. Whatever the case, i want the hesitation and clunk on the shifts GONE.

opinions?

i should clarify im probably going to do the tune either way... im wondering if ill need the shift kit as well or will that be too much.

IMO a shif kit corrects whats wrong with the tranny to begin with. Get the shift kit. If you get the Transgo hd2 kit use the mild settings ie (one washer in the lower accumulator housing).
using hp tuners, start with stock line pressure(adjust according to your liking) then your shift points, torque management removal, etc. The hd2 kit will take all the slop out of the tranny. you will have quick, firm and crisp shifts. instaneous downshifts when you need it.

is this a 4l80e if so your a head of the game here. and do the trans-go hd2 kit plus the tune just remove the t.m. and the adaptive learn,

i was looking at the B&M shift kit, is the trans go HD2 a better one? this is a 4l60e, not a 4l80e.

[NEUMANNZZ]

The transgo is better.

i didnt realize how much more the transgo was, the B&M is like a $35 kit.

thanks, i got my servo from those guys actually.

is that the same kit, and do i need the stage 2? edit: just realized they dont have a stage 1. also is the transgo install any different than the B&M? i was planning on using this writeup.

:dunno: i have a 4l80e shift kit for my truck but i'm just going to pay someone to install it that way i am 100% sure it was done right don't want to mess anything up.

[JoeliusZ28]

i guess i prefer to DIY... ill have to see what i can find on it.

as do i , but breaking something in the trans will end up costing you atleast a G to have it rebuild right .:nono: not me.

[JoeliusZ28]

maybe ill just leave it alone then.

labor is only like 200 bucks to install the shift kit. money well spent.
