I just started driving the corvette 2015 Z51 A8 to work and back recently (before it was a weekend car less than 50-100 miles per month) and have noticed almost a slip of the gears or a feeling it is between gears from 1st to 2nd. When you are gradually pressing on the accelerator from a stop it is fine in first gear and the transition to second gear especially if you let off the accelerator momentarily it really drops hard into second gear and jerks forward almost like its in neutral and you just dump it in gear at 2k RPM. This happens probably once or twice per week, any ideas what may possibly be causing this?

 

Does it do this only after a cold start or after you've been driving for awhile?

Have you had the triple flush performed?

 

It just happened today the car was parked for roughly 45-60 minutes after driving 10 miles all temps were up and in normal operating range. I do not know if it has had the triple flush or not so this is probably worth looking into with my Chevy dealership and have them pull up the service records. I have owned the car since mid 2020 and it hasn't shown any other of the characteristic items associated with that (Rumble strip sounds, RPM fluctuations at higher RPM's). Another item that always happens on a cold start is it takes 1 or 2 seconds before dropping into reverse or drive I am guessing this is normal, correct me if I'm wrong.

 

It has nothing to do with the fluid. The A8 is an adaptive learning transmission and every once in a while, if you don't drive it like you stole it , you have to do a relearn process

Take it to any reputable Trans shop or dealer and have them clear the TRANS ADAPTS and do a Garage Relearn Procedure . They will know what it is. The trans will shift funky for about 100 miles until it relearns what pressure to use at each RPM shift change that will produce flawless shifts . During this period you need to drive it at varying speeds, ie hold the gas pedal down so it shifts into 2nd at different MPH ....
