SOURCE: 1990 f150 transmission up shift to early

Sounds like the passing gear cable is out of adjustment. Get a shop manual and see what the specs are on how to adjust it properly. It is a pretty simple fix.

2004 ford f250 superduty 6.0L dsl tow haul light flashing and doesnt want to go into reverse


That light means that the shift points have changed on the transmission. This is to get better economy when hauling. If it wont stop flashing then there is a valve in the transmission that is bad or sticking. You will have to have it removed and overhauled..

I have a 1997 Kia Sportage (#KNAJA5278VA787759). The automatic transmission used to not shift into overdrive at 60 km/hr, but only after the engine was warm--after about 5 km of driving. The problem...


I had a simular problem.
Ended up changing the themastat and the gears changed into overdrive when the temp. got to normal running.
Be carefull that you get right thermastat though. You want one that reaches the normal working Temp as soon as possable.
Hope this helps.

4l80e trans.had no overdrive,replaced unit with reman. same problem


The shifting, including that of the overdrive is computer controlled. It's even possible that the tow/haul feature has been activated through short, or such. The tow/haul function deactivates the overdrive, and raises the pump pressure in the transmission, causing it to shift harder and at different points. You might want to look into these.

Tranny wont shift out of 3 gear it drives fine just wont shift in to overdrive or when you punch it it wont shift down


Is your tow/haul button on? If not, it could be activated erroneously. It'll keep it from shifting into overdrive and locking the torque converter, and also keeps the transmission from shifting more often. If this isn't the issue, then you'll have to look into your computer, as the transmission shifting is controlled by the computer. The transmissions were the weak points on these trucks; only good for max 200000 miles, so if you're getting close, keep that in mind.
