Possible transmission Solenoid failure
My TX has only 2 solenoids, one for Overdrive one for the torque converter lock up. It is a chrysler A-500 from 1989, also called the 42-RH. Basically a 904 with a overdrive housing tacked onto it....

If the solenoid were failing, then it would not just engage and disengage at only 35mph right? Today I was holding 40MPH warm and OD stayed engaged, acted normal. Did not get it upto lock up speeds(47mph+)
I checked resitance on the throttle position sensor through outs its range. Very smooth, but I do not know if the resistance range is correct. 1.36K ohms to 4Kohms.
Manuals say to check voltage output through range. Backprobing connector proved curse inducing.. DO not want to pierce wire insulation.
Also suggested my Speedo cable can be in need of lube, and bouncing. Vehicle speed sensor is inline on Speedo cable. Will relube tomorrow.
