Transmission tune testimonials
Thinking of a AT tune for my 08 LS3. I’ve read lots of information but not many testimonials. For 300.00, it sounds like a wise move (1000.00 for both dyno and trans…on the fence) but I’d like to hear from guys that have had it done and what the outcome was. My complaint is the lag between hitting the paddle and gear change.
And would you go to a tuner who specializes in corvettes or a tuner who generalizes in modern American V8. The tuner I’m looking at is the latter.

I went to a speed shop that builds and works on corvettes primarily. (Cordes Performance Racing, they are a vendor on this forum)
Had them install headers, cam, all the required goodies that go with that. They tuned engine and trans and what a difference. I exclusively use the paddle shifters now. Also did the F1 mod to right side paddle. I would say YES definitely worth getting tranny tuned

This is a good topic. The condition that you mentioned, isn't considered an issue and so I don't believe that it's "adjustable".
It's my understanding that the 8L trans has a different architecture to make the command-shift speed faster.
My 6L worked fine at light throttle but I felt there was room for improvement in shift feel at hard throttle.
I installed a Yank 3200 and a Transgo shift kit, which is essentially a recalibration.
and I'm very satisfied with how it works now. The TCC apply is night and day different and that's the main issue with this trans.
But the shifts aren't instant and I don't believe that they can be.
I really hope someone will chime in and address this issue of command speed.
How is the quality of shifts at hard throttle?

You guys may not have the right tuner. I get zero lag when shifting with paddles or letting trans shift itself(in sport mode) One big factor is don’t let your tuner mess with torque management, leave that alone. You’ll do damage to your trans. I notice a huge difference with the tune, but then again I feel we have the best tuner in the southwest here.
Zero lag in that I’m breaking tires loose between 2nd and 3rd and even into 4th if I keep the skinny pedal down…so yes I notice a big difference.

Here in Austin I did the dyno tune which cover also the transmission. Aikman did a great job. All shift were firmed up.
What I have been told is that when the transmission shift smooth that wears the clutch pack out faster since they are both are engaged same time 1,2 2,3 etc
The snappier shift the clutches are not together that long

I had a friend with an LSA blower swapped Chevy ss. He was always beating cars with a **** ton more than him and that thing just could not be touched.
He will swear all day long that it was all in the Tran’s tuning and he had ALOT of hours in perfecting the trans tune.
I would say based on his comments, there is some value add if you are a racer. If it’s just a normal car you drive with some power, then debatable if you will get the value out of a trans tune other than some more predicable shifts

Also it seems that the actual shift is a little slower with the paddles than in the auto mode. But this needs to be inspected a little more to be sure, that there is nothing different in the shift timing and a couple of adder tables.

100% worth it, tell your tuner to enable TUTD so you can pull back to your desired gear, hold it, and auto upshift in sport. Trans tunes wake these cars up huge when their stock. First thing I did to mine, you'll def notice the difference.
Heres some good info on TUTD

I personally won't enable the WOT auto upshift in TUTD mode, since I'm a man-child and I want to keep the selected gear when going sideways during winter (or wet conditions) and adjust the sliding angle with the go-pedal. In those slippery conditions one could hit the rev limiter very quickly, and an unwanted upshift with rear wheels suddenly spinning way faster unexpectedly would cause plenty of trouble. But that's probably just me, because the vast majority won't drive their 'vettes even in the rain and even less would do that during winter.

Now there's still some work to be done to adjust all downshifts in TUTD mode to get the engine automatically into better rev range even when not actively changing lower gear...
