Transmission / Torque converter compatibilty?
 

I'm trying to figure out which transmission/torque converter to use in my 240D, which I'm putting a 617.952 into.

My choices are:

1) The original 240D transmission. I think it works as I have the PO's service records. Unfortunately the torque converter has a broken tab, and I don't think it will hold up with one tab.

2) The transmission that came with my 617.952 (from a '82 300CD). It has a torque converter with it that seems to be in good shape. The bad news is this tranny was set done on top of a small rock that penetrated the pan and chipped a piece off the corner of the valve body (I didn't do it, it came this way). I'm thinking of JB welding it back together and trying it anyway. :eek:

3) The transmission in my '78 300D. But it has a mechanical kickdown, not a cable (like from #2), and I don't think I can get all that crappy old linkage to function properly, especially with the electrical cruise control.

Which torque converters would be suitable for the turbo engine? I'm not sure a 240D converter is appropriate, and I don't know if the n/a 300D unit will fit the 240D transmission. The 300CD converter (for a turbo engine) will definitely NOT fit the 240D transmission, as the tabs have much smaller slots, and will not engage the pump.

Any suggestions are welcome. :confused:

I know some people here have done similar swaps...I'm headed to the local U-pull-it this weekend, anyone run a n/a torque converter on a turbo? What's the difference?
