A couple of weeks back on my way home from work, my transmission began shifting in and out of over drive, ie jumping from ~3k to ~4k. The button on the gear selector seems to work just fine. If I use the switch to disengage OD, my RPMs don't jump around and the transmission stays in gear just fine.
I immediately thought I was a bit low on tranny fluid, so that night, I checked and added about 1/2 quart. It was a little low, but not scary low.
That seemed to have resolved the issue for a few days, but the issue came back, likely didn't really go away. So began my google search for "montero|pajero overdrive problem"
I seemed to find two primary culprits, The transmission temp sensor or the overdrive solenoid. Upon visual inspection, I don't see any obvious issues.
The temp sensor is involved by not allowing OD to become active until the trans come up to temp. So if the sensor is not working properly, the trans will never appear to get up to temp.
What is strange is that during my morning drive (about 20 miles of freeway) it seems to stay in OD just fine. Car sits all day in a garage (no AC, but not in sunlight), and then about 2/3rds of my way home I start to have issues with the transmission slipping out of OD.
Any thoughts on how I can troubleshoot this issue, or where I should focus my efforts? One thought is to just ride it out until the issue becomes more consistent then try to trouble shoot further. Today, the OD totally stopped for about the last 5 mins of my drive, so it could be permanently out.
Anyone else have any similar issues?
