It's been flawless for a couple of years. All of a sudden it won't shift right. Here are the EXACT symptoms & what I've checked. What's next?
Won't upshift any gears until 4000-5000 prm but does shift.
makes the 1-2 shift about 27mph
makes the 2-3 shift about 46mph
will make the 3-4 shift around 75mph if you back off the gas a little
Immediately locks the converter after it goes into od.
IF YOU WIND THE MOTOR TO LESS THAN SHIFT POINT & BACK OFF YOU GET NO ENGINE BRAKING BUT IF YOU MANUALLY PUT IT IN THAT GEAR YOU GET ENGINE BRAKING.
It's been doing this for about 2 weeks while I ckecked fuses & stupid stuff.
One morning when I left for work it shifted perfectly, like it used to, all the way to work in mixed driving.
I was afraid to shut it off. lol
When I went to lunch... no shift... back to what it had been doing.
THAT made me think it's electrical but just a SWAG
I did the self diag posted in the FSM & all 10 binks are the same.
What's next??
NO I DON"T WANT A 5 SPEED!!!!!!!!!!!!!!!
Thanks in advance for any help.
