Here's why I changed the seal. We had to stand it on its tail and lift the torque converter up and down with an engine hoist to get all the splines and the front pump to line up. The good news, for you guys who have to do this, is that when it is all bolted up snug with NO oil, the torque...

I went from the transmission on the ground to bolted up!!! We had to stand it on its tail and lift the torque converter up and down with an engine hoist to get all the splines and the front pump to ligh up. The good news, for you guys who have to do this, is that when it is all bolted up snug...

Dextron III, 10W, 15W40, ... This discussion will never end!! For me, I'm going cheap ATF this flush and synthetic on the next. Having paid $375 for a 16 mile tow, $500 for a replacement transmission and gone through this, I'm going to go with ATF not 15W40 which is what is in that bucket of...

RE Transmission oil: http://www.steelsoldiers.com/showthread.php?123048-Allison-Seals-and-Oil Shell Rotella 15W40 is what I use in the engine because it is recommended by several over-the-road guys.

Watch out for the famous GL forklift! I have 2 M105s and both have frame damage and broken wasp excluders on the relay valve.

I've driven two "vehicle does not run" trucks home, one 500 mi. and one 1800 mi. They both had dead batteries. I think if I try that again the odds will smack me up the side of the head; there are so many problems I could have had, besides bad brakes, a blown tire and a lost water pump belt in...

I didn't ask, but from past experience, just pull the plug and set it aside with a catchpan under the pan. Then, without starting the engine, turn the transmission over a dozen times, or so. You can do that by disabling the engine and cranking it. After that, don't worry about it. I have the...

While getting ready to put the transmission I got from Glen at BFR Metals into my M923A1, I noticed that the front seal was starting to leak; not surprising with a 30 yr. old transmission. I have spent literally hours getting the part number for that seal: Allison # 23016643. Napa says that’s a...

A different kind of harmonic haunted me while ferrying my M923 from Ft. Benning, GA to Ft. Worth, TX. I'd get going about 50 (which I later learned was only 45) and I got this horrendious noise that sounded like something in the power train was ripping itself apart. I pulled over and crawled...

If ya can't fix it, use it: put a couple of potatos in the glove box along with an open pocket knife. After 10 miles or so, ya got sliced potatos. If ya want diced potato, use a two bladed knife. It sounds like a sideways shimmy, not a badly balenced tire. Out of balance tires don't usually...

I have been considering swapping torque converters, but there are at least 3 years different in age and they come from different models of trucks. The other thing I am seriously considering is beveling the end of the center tube/shaft of the torque converter. I can see that it has been...

That worked on the pull-out unit, twice, but not on the replacement unit. I felt it 'click' on the 2 sets of splines. It stops about 3/4" to 1" from going in far enough. We had the transmission lifted and lined up when we realized we had a problem. We dropped it and pulled it out in order to...

Follow up and thread closure: If you can't reach a wrench in to the accessory drive (see Gamagoar1's response), you can bar it from the generator if you over-tighten the belts, BUT the method we settled on it to simply bar it from the bolt on the front of the crankshaft. It is a reasonably...

I find it interesting that I got 68 views, and 0 replies; am I the only one that ever pulled the transmission on an 900 series truck? The answer is 'no', the engine is supported in the very back by a mount on either side and one in the center-front.

Can anyone tell me what the secret to getting the torque converter back into the automatic transmission is? It was in place when I got the transmission, but it fell out while we were moving it around. There are 2 sets of splines that have to be matched up and a square, like a 'double D'...

I have searched the TMs but can't find the answer to this question: Do I need to support the engine on the front or the back when I separate the transmission from it? On civilian trucks that I have worked on the answer is a resounding YES, so I am concerned that I might damage motor mounts or...

This is what works for me. Because of bad weather and my son's girlfriend taking him away from the project (I think they went ring shopping yesterday) we haven’t gotten much done in the last 3 weeks. We started out trying to bar it from the accessory drive, but as Gamagoat1 pointed out, it is...

Thanks. I learned from the best how to "farmer" something, so, with your good advice I'm sure I'll get it done. BTW, you, thesledge in Black forest and I need to get together some time. mactiredearg is close by too. Arlyn
