Hello All,
In an attempt to do my "good deed for the year" I took on a 91 240 with 175K to repair. It had been very much neglected and belongs to a friend of a friend some 120 miles away. They had brought the car to various upstate NJ mechanics who replaced the AMM and ECT all to no avail. With typical male hubris, I offered to drive the car to my home in upstate NY and fix it. I drove it home on Tuesday. Other than the car being w/o od, it ran well enough to get me home.
I cleaned the throttle body and IAC as well as a host of other odds and ends. The OD wasn't working so I swapped out the relay and flushed out some of the black tranny fluid with 3 gallons of new Walmart brand Mercon Dexron.
Much to my dismay, my initial drive test resulted in a slipping tranny. I checked and rechecked the fluid level which actually seems a little high - in the max range after only 10 minutes of running back and forth in the driveway to conclude the transmission was slipping. Btw, I did check it with the car running. Any suggestions on this. Do I drain the pan and put the old tranny fluid back in? I checked the kickdown cable and it moves freely. I did replace the shifter bushings by removing the entire linkage and wonder if this might have something to do with this problem. Any suggestions are very welcome.
One other thing to comment on: When I did the flush the pumping rate was rather slow. I've flushed my other 240's a number of times and the rate was approximately twice as fast, actually tough to keep up with replacing fluid as fast as it fills your gallon jug. Not so with this car. Keep in mind that during my 120 mile jaunt, with the exception of the od, the tranny worked fine.
