Transmission issue

Crazy Drywall Guy · 05-29-2021, 07:54 PM

2018 Camaro SS 21,000 miles, Fbo, transmission has been Prey tuned. Car has been running great until recently when I'm going 20-25 mph and floor it expecting it to down shift the rpms redline but the car won't go until I let off and mash the petal again then it takes off. A couple times the car kinda shakes /shudders when it down shifts like it wants to go but until I let off the pedal and mash it again the will engine just redline. I've discontinued and low speed down shifts of course. Anyone had this problem?

Have you reached out to Pray about the transmission tune?

If you have an HP Tuners MPVI2 device, you could data log the issue as it is happening, then send him the log, which I'm sure would speed up problem resolution.

I thought about data logging but I don't have a laptop,I used my desktop computer for the tune originally. Maybe I'll have to shove my desktop in the passenger seat with a power inverter 😂

Haha, don't forget to strap the sucker in

My laptop ended up in the footwell a few times when I forgot it was the "passenger".

I believe this issue has been resolved. I think it had something to do with the Soler performance throttle controller,I always run it on the Ludacris setting. After switching it to other settings the issue has disappeared.
