Engine + Driveline / M42 build complete -- tranny install problems

« on: December 01, 2011, 01:07:41 PM »

@vpilarry -- Unfortunately, I'm sure its in all the way. The TIS manual says the distance from the TC mounting plates to the edge of the bellhousing should be ~30mm and mine is. I also took it to a transmission shop to have them verify that it's going in all the way -- they verified that it was in fact, fully seated.

Could it just be the angle at which I'm putting it on? It's such a pain since the trans is so dang heavy, plus the engine hanging on the hoist makes drawing the two together at the correct angle difficult.

Any ideas as to a better method for putting this on?

When the housing is bolted flush, I can't crank the engine by hand (using a 1/2 inch drive  2ft long breaker bar on the crank bolt). If I loosen the housing a little, then it will turn. Should the crank be easy to turn this way after tightening the bellhousing?

Hi all,

I've finished a stock rebuild of my E36 M42. It's on the hoist and ready to go -- but now I'm having major issues getting the automatic tranny attached.

Here's what's happening:

1. Seat the torque converter.
2. Carefully attach the tranny to the engine and tighten bolts so that bellhousing is flush with the engine.

At this point, the TC is pressed up against the flexplate -- no gap. The TC cannot be rotated by hand, due to the contact. If I loosen the housing bolts slightly, then I can rotate the TC. Also, with the housing flush, I can't turn the engine over by hand.

The Haynes manual says: "Once the engine and transmission have been mated, it is no longer possible to turn the torque converter to allow re-alignment". Does this mean that contact between the TC and the flexplate is OK?? Shouldn't the engine turn over if this is properly installed?

I'm at a loss. A shop looked at my trans/TC and said the TC is seating properly. Any ideas as to what's wrong?

Thanks in advance.
