My next day I plotted a longer drive and hope to also explore the reverse oddity. Backed out of the driveway and off I went, everything as smooth as glass. Then drove up to about 45 and suddenly there was a un solicited downshift to what felt like second when I took my foot off the gas gave it gas and it went back seemingly to normal, the downshift again after a few hundred feet. I slowed to see if I could tell what was happening and when I shifted back from drive to park, the car was still in drive when the shifter was in neutral and reverse, and even in park it seemed engaged even though it will still crank from park and immediately goes back to forward pull against park.

My thought was the linkage was messed up or slipping. I got her off the ground and had a friend work the shifter (engine off) back and fourth every which a way and it clicks into the mechanical gear with perfectly, you can not make it miss shift with the shifter.

I have studied this online for a few weeks trying to gather as much info as possible. The only code I get with my OBD reader is 1722 but I'm not a mechanic and maybe I didn't do the “a drive” replacement properly. I really like the car is had a wonderful paint job, original and great interior and ac and sound but I need to fix it without a huge cash layout. The cars have low market value mainly due to the repair cost of the vehicle, and this one will be a heartbreaker if I have to “essentially give it away”.The clutch plates in the transmission only have about 80000 mile but the fluid was solid black, the inside the case was beautiful and only had to replace a few gaskets and no berings. Clutch plates in the a drive looked new...... Thanks for any advice or help

If I take it to a transmission place for their analysis what type of analyser do I need to be sure they have to get me the proper analysis... Will P
