When I'm on the highway, I can't even get up the smallest grade without coming out of lockup. It'll even kind of "drift" in and out of lock up. What's going on?

Rossler, PT3400, 3.42s, EW tune on a stock motored single turbo car. WOT runs EXTREMELY well, as seen at the track. It bangs sweetly from gear to gear. Around town is just fine, too. What should I set up the Atap to look at when I go out today, to find out what's going on?

Thanks!

Same problem here before MTI reprogramming. You can install a lock up switch. I have the wiring diagram if you need it email me at larry98@ev1.net.

 

Thanks, Larry. Sent you an e-mail.

PCM still needs work and that should fix it 100%,it did on my car.

 

Thanks J

 

Had a similar problem with my car. I would get intermittent locking and unlocking on the highway. I had to adjust the midrange misfires on my car. Problem completely went away.
