Question about 1991 Ford Econoline
I have a 1998 ford econoline 150 .6cyl . the tranny does not shift properly always shifting from overdrive to dr, and seems to flutter going from 2nd to drive . just seems to be all over the place when shifting from second to drive .. any ideas on something i could try for an easy fix . or do i need a new tranny or rebuild . and modules or sensors i could change .. any ideas? thank you ..
This will sound odd, but if the fuel filter hasn't been changed in a long time replace it and check that air filter isn't clogged up. If this isn't causing it you can try changing the fluid if it's been neglected and add TransX.

Your transmission fluid contain water,thats why the colour of the fluid changed to pink.And of such the clutch is slipping causing the engine to reve up before shifting - Check transmission cooler.

I have that exact same truck and transmission and My Transmission did the exact same thing about a year ago and there was some kind of snap ring inside the transmission that broke. I originally thought it had to be an electirical problem because the truck shifted fine until OD or if i turned OD off. The 4r70w is a light transmission and i would suggest you have a shift kit put in and they make a heavier kit to beef it up.. Sorry its probably not the new you were looking for.

my overdrive light is flashing due to a shattered speedo cable tip. check your fluid level. you may have to change the tranny filer and redo all the fluid.

Same problem, only 2nd and 4th gears (92 ex, auto with 175k). Missed diagnosed by previous mechanics, replaced engine coolant sensor. Couldn't figure that one out? Went back because problem reoccured within a week and now much worse than before. They diagnosed as bad TCM this time and want over $700 to fix, in addition to the other $300 I spent. Said a resister was burnt on the board. Did not believe them. I pulled the board myself (located under the pass. floor mat, disconnect battery, remove four screws and pull the wiring out and open it up). Looked at board myself did not see anything wrong, but does not mean that it isn't bad. Research on the web said that it might be a bad release solenoid on the shift handle? It's located in the center console underneath the plastic covering near the park brake. That checked out ok. So I ordered a TCM from allcomputerresources.com ($155) should be here in a couple of days. I hope this helps me and you. Good luck.
