When I put in my M410 last January in horrible weather, there were a few things I neglected... The main one being, I didn't hook up the overdrive figgering I wouldn't need it for a while. Its a real pain in the ass to get them wires on the 4th gear sensor when the transmission is up in the tunnel. Hook that thing up right the first time even if the weather is bad and its so cold you can't feel your fingers.

As for the clutch... As I've come to learn, the pedal box in a 140 auto does have a hole to accept the bolt for the clutch pedal. But, on a std tranny car, said hole is built up with an extra plate of steel for strenth. Auto cars do not have this, and you need to do something about it. Ideally, add the reinforcement, or use a pedal box from your donor car.

Mine has become cracked. I put a steel plate in there and bolted it down tight today, and it seems to be OK for now. Much better than its been for the last year actually...

In the end, I changed the fluid in the transmission today, got the OD hooked up and it works (I had never tested it, so I'm happy), and fixed the clutch pedal if only temproray.

Off on a ~200 mile round trip to the southern side of Denver this afternoon/tomorrow. We'll see how it holds up...

Matt,
How true about access to the 4th gear switch! I put a pig tail on it when I put the tranny in, but it detached when I started messing around with some other wires. I had wanted to cut an access port in the top of the tunnel, but then the heater turned out to be in the way. Loosening the bolts on the cross-brace makes it a little easier to get your fingers in there, but not much. I think I ended up dropping the whole brace. I had read about the clutch pedal situation on this Board and so managed to do it right the first time. Wish you continued luck with the tranny.

Sounds good Matt.

I opted to keep my auto tranny although definitely not my preference. Just did not have the time and energy to hunt down a doner car and deal with it all. Also, the risk of getting a worn-out manual tranny seemed high and too much bother. So I pulled the auto tranny and had it rebuilt for $1200. Installed a heavy duty oil cooler (couldn't find fittings to original cooler on base of radiator) and filled 'er up with Redline auto tranny oil. So far so good. Still have to get the wiring hooked up to the neutral/reverse switch.

Glad your swap worked out well. Still kinda wish I'd done that, but it's too late now.

Later,
Al
