Won't let me drive?

D.T. · 12-28-2008, 06:40 PM

Is my 1997 Jimmy a second generation?

Anyhow, I noticed this winter when the ambient temps are around 0 degrees that the truck will not let me take it out of park for about 30 seconds or so after starting.

I figured out that it has to warm up before it goes into overdrive also.

Am I going to have a problem with my Jimmy or is it normal? Does the ECM lock out the drive until the temp gets up to a certain point?

Never heard of such a thing. You checked your trans fluid level? It might be low if it's acting funny.

Zeeke98 · 12-28-2008, 08:10 PM

Uh yeah, 97 is a second gen. 95-04's are second gens. 82-94 are first gens.

yeah the tranny fluid is too thick when it gets cold out and needs to heat up and thin out so it will shift good.

What does your engine temp come to after warm up? You probably should be running around 200/210ish with a stock 195 tstat.

Also assume this is Delphi radiator with no clogs and something that has replaced the dex cool. The radiator warms the hydraulic fluid.

I have checked it, it's in the normal range. Would parking on a slight incline make a difference? I do not know how many miles are on the tranny fluid and filter either.

I try to go, but when I push in the AT shifter button with my thumb and the solenoid just clicks for about 3-4 times (foot on the brake), won't go into reverse. No codes either.
