I have a question.

When the Suburban sits for a bit, I start it up and give it a minute to run. When driving, it stays at high RPM from 1st to 2nd then clunks into second. also, 2nd into third but not as bad of a clunk.

Now when it warms, it is not that bad. it seems to shift smoother and no real bad clunk.

The transmission has 30k on it, but the truck has not really been driven for about 3 years.

Could this just be a common thing,
could it be torque converter,
Or could it just be because it is cold??

 

I'd go ahead and change all the fluids first.

 

I'm going to change the Trans and DIff fluids.

I read it could also be caused from the diff/gears, thought?

 

I wouldn't think so. Only reason I could see is the old oil in the diffs causing more resistance up the driveshaft, making the trans think it's working harder. Doubt it though.

Fluids first an then maybe look at the trans needing a filter change or new pump if it keeps happening.

 

I'm going with it not warming up and the fluids are thicker when cold causing it to hard shift.

 

Start with the fluids as others suggested, if that doesn't fix it, it may be the vacuum diaphragm on the side of the transmission. It's on the passenger side...inspect it for damaged hoses (cracked and or dry rot)..

I'd drop the pan and do a filter if/ when changing the trans fluid especially if it's service is an unknown.

 

Newer model 4Runners will be a pain in the dickhole and very expensive to lift/make decently off-road capable.

Don't know what you plan on doing with it, but if you are..

 

If I get a 4-Runner it would be early to mid 90's most likely. Probably go with a Cherokee or truck though.
