AW-70/71 Transmission problems and solutions. 200 1990

thank you for that lenghty reply. I just noticed that you wrote it only 20 minuted ago. Here is my update. I actually just posted a new thread on my latest question but here it is again.

I wound up buying a new used tranny from the local junk yard for $200. Exact same model. I had to fight the parts guys every step of the way everytime I asked for a tranny from a different model. They kept insisting it would never work. So when I found the exact same aw-70 model, I gave up trying to put in a beefier model. The replacement has been sitting in the yard since 4/96 and also come from a 90 240. I found it through car-part.com. The fluid looked real dirty so I plan on flushing it initially and then perhaps in 500 miles. The output bushing was sloppy and the seal was gone. I replaced both of them as well as the input seal. Put in a new tranny filter and gasket and sealed it all up. The parts came from fcp groton. They got me the parts the next day and were very helpful (I think the most inexpensive as well). BTW, the tranny filter kit only came with one gasket. Luckily one of mine remained intact.

Here is my latest question. The fit between the output flange and the bushing is really sloppy. Seemed as bad as what was there before. About 0.030" slop in the diameter. I discussed this with several of my mechanic buddies and came to no definite conclusion. Eventually, I decided to just put it all back together. Now that it is all bolted back together, it actually doesn't seem so bad. But I am not impressed by the design. I had thought about making my own bushing but I just don't have the time. The output flange bolt on both the old and new tranny were loose. I may decide to loctite it.

So tomorrow or Sunday I will put it back in and see what happens.

Do all the AW-71/72/L models have the crank sensor notch in the bell housing? Anyone ever modify a bellhousing by hacksawing a notch?
