Well I checked numbers. Original number 722 303 02 053794 new number
is 722 303 02 222285 is said to be out of an 81 300sd. My car is one
of those only 85 MPH cars but it used to do 85 quite well.
I just came back from another drive. I hooked up a push button switch
to my kick down solenoid and 12 volts so I could energize the kick down
any time I wanted, took it for a drive, I found that I can put it back
into 1st by pushing the button while pulling away from a stop, and I
can put it from 3rd back to 2nd by pushing the button. I figure the
kick down system must not be stuck. Tranny just don't like 4th
I will just wait till tomorrow and take it up with the company that
sold this to me. My biggest fear is that they will want to refund or
exchange the transmission with out a diagnosis and it would be a shame
if there was some simple thing that could solve the problem while
tranny is still in the car. I will at least see a transmission shop
befor I change that box again, I am getting too old for this under the
car stuff, though I enjoy it, my neck is still stiff.
Thanks to all who have answered my post, I appreciate you.
