Hey everybody, I apologize if this has been asked and answered already but I couldn't find my exact problem after searching. My '89 FJ62 develops some wonky shifts after driving for about 15-20 minutes. It's fine cold, but after a while the shift points get really high, 3K RPM or higher and if the engine isn't under a load the 2-3 shift kicks really hard. The accelerator pedal also gets "soft" at this point, it loses the typical mechanical friction feel. Trying to shift manually does nothing. I just had the transmission serviced and all new hoses and fittings installed, this problem existed before the work and is still there after. Any thoughts on what could be causing this would be appreciated. Thanks!
Update edit: Thanks to @EscapeWagon62 I learned about the kickdown cable and what it does. I believe that as the engine and transmission heated up the cable was expanding in the housing causing it to get stuck at an open throttle position. Using a cable lubricator I forced a bunch of cable lube down the housing until the cable moved freely again. Between that and the party trick the truck is shifting better than I remember in the last 10 years.
