Hello,

I recently did a manual to auto swap into my camaro. I have been having lock up issues, where the converter would not lock at all. I had my buddy look at the tune and got it to lock.

That is the tune that i currently have on the PCM. I have the misfire tables completely disabled and I have it only locking in OD. When I had it on the dyno the other day. and I commanded the PWM and the TCC lock solenoid in the HPT scanner, it was not having any issues locking or shuttering on the dyno that i noticed.

So here is the main issue, when I am in OD cruising down the highway and I apply a little more power to get up to speed while the converter is locked, the car will shutter and the rpms will come up by about 100 or so and settle right back down when i apply less pressure on the pedal.

 

Its a fuddle of some sort. I think it is the 3400. I am not sure.

And when i put the auto tune on it for the first time. I did do, write entire.

 

Joy, I don't want to jack with the pressures. This tranny is stock (i need it to last the summer), but i am planning on putting a shift kit here in the next couple of months.
