Sounds like 2nd gear in the transmission is slipping. Cars usually shift at 15-20 mph from first to 2nd. First check the trans fluid.

You need a new neutral safety switch. The car does not know what gear it is in so it goes into safe mode and sets off in third gear. There about £150 new but i got one from the scrap yard for a fiver. There is a guide on one website that shows you how recondition the switch but can't remember which one.

1997 GMC Jimmy, Won't go into reverse,but all other gears work,ok.


Check the automatic transmission fluid color.

It should be lite pink and there is ZERO odor of burn friction material.

TOP OFF is it's low on ATF

=====

Have some one the check on the reverse light when you put the truck into the reverse gear.

NO reverse lights then the neutral safety is falling.

=====

Check for free play on the gear lever. Pay close attention on the transmission end.

USE clear to remove excess dirt.

=====

Inspect transmission pan and the floor for ATF leak.

Please rate my answer if it's helpful to you.

Cheers,
