Does anyone know what the problem on my 2008 chevy uplander could be. after putting in a new transmission because the other failed, it now overheats even after putting in a new thermostat...help......

Mr_Shiftright

Are you quite sure it's going through ALL the shifts?

milo4444

He says yes, even the scanner says all is good but it is still on the scanner saying it is running hot. Doesnt go over the half way mark on the gauge, but before putting the different transmission in, never went over just past 1/4 mark on the heat gauge.

Mr_Shiftright

Overheats when? At idle only? At speed only? Or all the time no matter what? Are we sure the cooling fans are operating properly?

milo4444

The gauge goes up as soon as you start the engine,
like within a minute or so.

Mr_Shiftright

Well can the scanner give the exact temperature reading? If it's in the normal range, I'd just leave it be. You want an actual number, not a point on the car's instruments.

Overheats within minutes. Not the normal range.
