Tranny won't kick down into passing gear

My wife has a 06 H3 with 80,000 miles, Transmission won't kick down into passing gear. Where should I start looking to repair this???

Ok, I'll do what I can here, I'm a old school off roader but I do believe your Transmission is controlled via a computer. Prob knows when to shift by throttle position and 100 other things all going on at once. With that I would first check for a bad fuse. Do the easiest things first. Does it do it no matter if your in Drive or 3rd? Check your fluid level? Check for unplugged, broken or lose wiring. Could be anything bud, always check what you can before you take it in so you don't get taken...............................

Shift solenoid ? 06 H3 has mentioned that before....

yea, I only had 2nd and 3rd. I killed my shift solenoid. Slow to get up to speed and high rpms at freeway speeds. Its basically limp mode.

Its an easy fix, I believe it was from the amount of heat my trans was pulling, now I am running much cooler with my trans cooler.

By "passing gear" I'm assuming you mean a 3-2 downshift? Or are you talking about a 4-3 downshift? Does it downshift if you manually select the lower gear?

Thank you all so much,Max it is 4th to 3rd.It did shift down manually. I drove it yesterday and it acted perfect,no codes, fluid looked good. I am going to disconnect the battery to see if it was a computer fart or something. Could be the wife is crazy but we will see…. lol
