1997 ford escort quit shifting onto overdrive

The OD solenoid in the transmission or the transmission control module is defective. It's also possible the torque converter clutch plates are worn. That's where over drive comes from

What causes aChevrolet z71 to not shift into overdrive and take off in 2nd gear after I change my transmission out 5.3 liter motor with a 4l60e transmission 4-wheel Drive

If you are lucky, bad shift solenoid (common failed part) may cause it to start in second. Other problem of no overdrive (ie: no torque converter lockup) could be as simple as misadjusted brake pedal switch or TCC solenoid. Where did you get this apparently bad transmission?

1997 Chevrolet Silverado Z71 p0758 Won't shift

P0758 code is shift solenoid B electrical /2-3 shift solenoid circuit electrical, It better to inspect the wire going into the transmission they have a tendency to leak transmission fluid into the circuit make inspection for proper connection if you decide to replace the solenoid you still need to inspect the circuit for proper mating. If this solenoid fails and you wait to long to replace it you can loose the ECM due to the high power draw it takes from the ECM.

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.

I have a 1993 Chevy Z71 Automatice with Overdrive Upon excelleration it hesitates to shift but if I left off the gas and try again it works.

Normaly overdrive kicks in from 55 to 60 m.p.h. it sounds like its the tps, throttle positioning sensor.

it's attached to the left side of the carburetor passenger side, on a diesel same side. if the tps gets

loose, gets water in it or is bad you will have a problem shifting to overdrive. If you have done any

kind of engine work. and if it was removed it will need to be adjusted.good luck!

It is likely you lock-up converter. Try using Lube-gard trans additive for converter shutter. I know O'reilly's has it.
