How is the lpg delivered? Through the throttle body? I would say maybe you have a problem with a regulator problem or it also sounds like the timing isn't advancing. I don't have much experience with obd I ( is that what computer you have)

It's OBD II but not showing any codes. Yes the LPG is delivered through the throttle body, and I took it to an LPG mechanic last week to give it a tune-up and have a look over it.

It's been running fine on LPG for about 3 years.

I thought I'd help you out by reviving your old thread. haha. How did you fix your transmission problem? Was it the TPS, the solenoids or something else?

I bought my jeep with a similar issue except I had only 1st and 2nd when the transmission was cold. I had to replace the whole transmission with a junkyard unit. The solenoids didn't work for me either. My transmission was so gunked up I couldn't even clean it properly to do a rebuild.

I'm at a loss, I would say its the cap / rotor or the map. That's only a guess.

Dunno, it just hasn't done it the last couple of winters.
I blame global warming
