The pump is located immediately behind the torque convertor, and is driven by two ears, or tabs, on the neck of the convertor. There is no shaft.

I just want to add my 2 cents by stating that Frank Reiner knows his stuff and has helped me out when i had clutch issues on my 240D manual transmission. His input was right on. Thanks again Frank.

Based on his comments of there being no shaft, I think you should take Adriel's suggestion and take the car to a different shop.

OK, let me explain this as he explained it to me this morning. Tell me if this makes sense.

There is a shaft that gets progressively smaller from the engine all the way though the transmission that, by time it gets to the pump, is smaller than your pinky finger. He says that shaft is broken at the pump so it makes a "ticking noise" that you can hear. Therefore, it doesn't pump fluid and the transmission doesn't engage.

Does that make any sense to you guys?

In a word, NO.

Again, the main pump, the front pump, the engine driven pump, is driven directly by the torque convertor. It is a gear pump. There is no shaft that goes all the way through the trans to a pump.

There is a secondary pump, a piston pump, in the tail housing of the trans. It is oriented at a right angle to the axis of the trans, and is actuated by an eccentric on the output shaft of the trans. If the car is not moving, that pump is not pumping.

Good grief! Hope you followed through.

I been in your situation. He said it be no more than $100. Called me later and said $640. I not knowing the law paid. Well, nothing fixed so went back and spent more money. After that, learned not to go with him.

So, when I needed a simple brake drum work done, went to a different shop. This time when over charged, knew the law. So, went down, business happened to be closed, so had A.A.A. tow away. Then came back, dropped a cheque off and went in the office and got my key. Fellow followed me and tried to get the key and get in a fight. I said I will leave the key, as got more, and proceeded out. Well, got to keep the key. Later found the brakes were an absolute mess, wrong hardware used, so shoes came off and locked up. If had done it on the road rather than pulling out, you bet there be consequences. So, went back, watched the same fellow that tried to get in a fight with me, fix them right.

I also had that shop in Phoenix give me trouble, but mostly my fault for being a push over.

The last shop was great and honest about the price. Then the second time changed their policy and got really reamed.

I think the shop is only accustomed to FWD chevy and ford transmissions, they do indeed use a shaft to run the pump, These MB ones are like the ancient and proven luddite version where 2 dog ears from the torque converter drive the pump.

While they may know abt generic automatics - I would be wary of them working on this car if they gave me that "shaft story"

That difference Zulfigar described is why in ' the old days' some cars were allowed to be towed with four wheels on the ground for a certain distance...and others were not... according to their owner's manuals...

Well, it's full of fresh fluid, has a new filter and still NO transmission action. Guess it's time to try and find a replacement tranny.

Might be a good excuse to look for parts car locally ... or someone who could provide all the stuff .... to change to a manual transmission..... these old automatics are really hard to find mechanics and parts for...
The manual trans.. pretty much bullet proof....

Bob, sorry to read.

I would suggest putting your location in your profile, even if just a general area, like Midwest. Then folks can see if can help.

Also, put in a W.T.B. for your location and need.

There is also a good used parts source up in the Northwest that will ship. Name slips me. They even had the 1985 model year California emissions transmission and got a good deal on it. Arizona was a bit far, so shipped to Tram and picked it up on the way back home from a winter road trip a year and a half ago.

Hope this helps.

eB:

Before considering replacement of the present trans, a few pressure checks are in order.
There are three pressure test ports on the right rear of the trans. A gauge (250 psi) with a hose, and appropriate thread adapters can be found at Harbor Fright.
The principal test is for the presence of working pressure. If there is no pressure, the first step is to remove the valve body, and to check it for a stuck pressure regulating valve.

In the event that the valve body is OK, trans removal will be in order. There is a chance that the aforementioned pump drive ears (lugs, tabs) on the torque convertor have been damaged.

Take it a step at a time.
