The Dodge execution could be better. A couple little things that could be changed probably would change the longevity and opinions of the transmissions by quite a bit. Valving, check valve delete, torque converter, more cooling, and not towing in top gear would probably would do it. Most guys just run them without a second thought, and problems crop up. On the other hand, some guys get some pretty high mileage out of them without too much problem.

Out here, I used to go to the lounges and little bars a lot more often, and as soon as there's a little snow on the ground, those diesels stay running half the night!

The NADP guys in Edmonton are pretty good. I had a more local shop change out the transmission for me. I noticed that it seemed to lose a little fluid, and it took me a long time to get around to taking it down to them. I think I was within a few days of my 3 year warranty when I took it back for an appointment to have them look at it. Had to leave it with them for a day or 2. The guy at the counter said it took a little longer because it was a custom transmission. I think they freshened it up, and adjusted it for me! Didn't pay a thing. Performs well, so I'm pretty impressed.

Probably similar work to Suncoast that I hear good things about. They build a really stout Dodge transmission, too.

 

All of the transmissions have planetary gear-sets. They are all four speeds, with locking converter. The heavier duty transmissions simply have more pinion gears in the planetaries than the 46. Here's some pics.
