Transmission shifting in and out of overdrive

[Lordsman]

I remember somewhere there was an electrical connection/switch that needed cleaning but can't remember where. Anyone know?

Search for TPS (throttle position sensor) adjustment.

Throttle position sensor, transmission temp sending unit, main electrical connector on transmission, electical solenoids in transmission..... just to start.

Cleaned the TPS... made no difference... . will do a search for TPS adjustment. Seems to start acting up when the transmission gets warmed up after 10-15 minutes of driving and goes in and out of OD at speeds over 30MPH. Fluid level is good.

Make sure the inline oil temp sensor is plugged in. It should be in the cooler lines going forward, on the passenger side, just about the bellhousing.

Oil temp sensor is on driver side, where front cooler line turns upward. I still say first verify operation of TPS is correct.

Mine was out of adjustment at . 3 I set it at 1. 0 and we'll see how it reacts.
Here is adjustment procedure.

Scroll down a ways to #28 and you'll find it if needed.
Thanks.
