A4 Transmission Tuning Hey guys i know many of you go with the Transgo HD2 shift kit, but i have an opportunity to HP Tune my 99 ls1 A4 almost for free with a friend. The question is how well would the transmission shift with an hp tune? I have 3:23 gears as well. Any response would be great
I'd get rid of all TM, engine and trans, plus the parts of TM thats not labled as TM.
A bunch of people are going to disagree with that but you know what, **** em.
Then run it, see how it shifts at all throttle positions.
If it lags try changing the desired shift time only at the point where it lags. I've had good luck with the upshift pressure modifiers, changing them can give you a smooth shift at low load and firm as load increases. I wouldn't go over a +10 change.
Base shift pressure vs torque vs gear can elimiate a lag and improve shift timing also.
I never had to make big number changes. And don't do anything to the force motor current or any other pressure tables.
And get rid of lock up in third, with the elimination of PWM TCC apply it feels like a shift/slip/shift when it locks in third, unlocks to shift, and locks back in fourth.
This is what every stock F Body TCC apply/release table that I've ever seen looks like.
You never feel lockup in third until you mechanically eliminate it.

TransGo doesn't make a kit called level three BTW. I don't know where people come up with this ****.
And TCC can't be mechanically eliminated only in third.
When I say you can't feel lock up in third until you mechanically eliminate it I mean mech eliminate PWM'd TCC apply.

well i got my car tuned today as i mentioned before, and the HP Tune did get me very quick solid shifts, not too firm but alot better than stock, car was able to chirp tires around 45mph with new sporty tires, the guy who tuned the car said if i wanted harder shifts that a shift kit and slight tune would be ideal, I also got a basic tune on other things on the car, anyway, my car is running a whole lot better thanks to HP Tuning software.

This was a B&m Shift kit. I had hp tune at 1st its not alike at all Go to the track with tuned tranny then go with a shift kit.

It's just the same as High Stall Torque Converters are often referred to as "Stalls".
Sunset'01Z's transmission is an ACE Stage 2 unit. It was built with a TransGo HD-2 Reprgramming kit. I'm sure you are aware that it deletes PWM mechanically.
He has not had a Tranny Tune since the build and therefore his 3rd gear lock up is still enabled.

TransGo does manufacture an HD-3 Reprogramming kit for the 4L60E... it is often referred to as a "level three" shift kit. It is the kit that will take a 4L60E to a full manual state.

Sometimes we have to read between the lines in order to understand what folks are trying to convey. It can be difficult, but exercising patience helps those guys in the long run.
I'm sure Wade had all the best intentions when he described his transmission and conditions in response to your original comments regarding PWM and 3rd gear TCC application.
This discussion has everything to do with the OP's Transmission Tune. If anyone has been paying attention they have learned that it is advantageous to delete 3rd gear lock up and TCC PWM in a High Performance 4L60E.
Hope that clears it up a bit.
