The boss's 2005 Lincoln Navigator 87,XXX miles
After sitting overnight, it will stick in a gear that isn't 1st and you have to give it lots of throttle to get it to move. (his words: it won't get out of it's own way) Something that he just mentioned is that some nights he parks it so he has to back out of the driveway and sometimes it is parked so he drives out of the driveway. When he backs out of the driveway, it sticks in a higher gear.
Also, it will shift hard 2-3. Not a clunking shift, but not smooth. Then 3-4 comes in within 1.5 seconds after that shift (may be normal, IDK) 4-5 is like silk and 5-6 is normal.
It has never done this before.
The recent work done:
Drained out the three quarts of oil, changed the filter, refilled with three quarts of Mercon SP. Brought trans up to temp with scanner reading temp and checked oil level. Changed engine oil and differential oil.
P0736 Reverse ratio mismatch.
The procedure so far:
Checked for codes, Checked TR switch after it gets to the shop and all switches hit. have not checked them running, but it moves fine now.
The procedure tomorrow:
Park the rig so it has to be backed out in the AM. Hook up scanner and look for something, but I don't know what.
WTF Mate? Did the transmission reset adaptations? With the scanner, it says that it doesn't have adaptations, but I don't trust things like that.
Is it sticking in reverse electronically?
Are there any suggestions on further testing?
