Thanks. I'll see if I can find someone with knowledge in my part of the world.

I've changed oil and both filters. Drove nicely for a while, and made sure the trans. and engine where good and warm. Same thing happened, limp mode if I push it, unless I put in Tow/Haul? Read that this trans. will wear as everything else, so now I wonder if the problem is just that?
I've got 126 ...

Thanks again, will do.

Thanks for reply. Solution?

Hi torchrider. I've got the same problem, and I'm brand new on this forum, and since this topic is kind of old, have you solved the problem? When I put it in tow/haul mode, there's no limp mode even if I put the pedal to the metal? 85 BHP mode. Without it, It goes limp passing aprox. 80mph.
