I recently purchased this 1969 230 from a repair facility here in Michigan. It has the 6 cylinder engine with an automatic trans. The car had had substantial maintenance work done to the tune of $8000 in 1995 and has had less than 100 miles put on it since. It has 88,000 miles on it and minimal rust for this model, this age and in Michigan. The story goes that the original owner had it serviced at this German repair shop and then died before he paid the bill. In the paperwork that came with the car I have letters from attorneys for the process of obtaining the title for the car. It then spent the last 17 years in a storage building, having been taken out on occasion to be freshened up. Recently, the repair facility was purchased along with the storage building full of dusty old cars, this one being the first to come out and be put up for sale.
Now to the problem at hand. The transmission is disengaging at stop lights and on occasion when the car is coasting. In the short amount of time I have been to drive it I’ve come to the conclusion that this only happens when the car is in the normal high gear selection. If I start from a stop in 1st, 2nd, or 3rd gear, or leave it in 3rd, the transmission shifts up as far as third and stays engaged throughout the drive. Only if it is in 4th gear, the trans will disengage when the car comes to a stop at a light. Upon giving the car some throttle, it will pop back into gear and resume forward. Reverse gear is fine.
Could this be a vacuum related problem or something more serious? The fluid is clean and clear and full. I guess my question is whether this is a common issue with this model and if there might be something I should do first to begin the diagnostic process. I have read the various articles and procedures on the B2 piston, but I am unsure if this applys to this model transmission. I have a fairly extensive history working on cars, mainly Volkswagens of all generations. With that said, I have very little experience with automatic transmissions.
I didn’t pay very much for this car at all. I am tempted to put some time and money into it to make this car work again so my wife and I can drive it on weekends and throughout the summer months. This will be an occasional driver.
Any help you may be able to provide would be greatly appreciated. Thanks in advance.
