Someone else put them there as GM did not. My shop was a GM warranty station for 15 years and I had intimate conversations with GM engineers about this very thing. When GM went to the solid converter instead of the split converter they also went to full mainline pressure in the converter, (...

Do a test next time you sell a deep Allison pan. barely stick the filter in the case and then see how the new deep pan fits. I bet it never touches the filter. It should bind and force the filter in the case. It won't.
Depends on where it gets displaced to. The filter is the B trim solenoid filter which is normaly open with fluid constanly flowing through it. Allison felt that some debris could get lodged in the solenoid and jam it. I saw that happen a week ago on a truck so Allison was correct in puting it there.
Watch out for the white tapered filter that sits in the upper half of the valve body. That is the half that only has 1 solenoid. The filter fits into a hole next to the solenoid.
The Transgo jr will help an '01-'05 by increasing pressure from 82psi to about 200psi, maybe a little more to the C3 clutches ( 3rd and 5th gear ) and c4 clutches ( 2nd gear ). Problem is there is not enough piston are in the C2 clutch piston ( 4th and 5th ) to clamp down enough. ( piston sq in...
They are made differently and in their own seperate plants. I like the fins on the Setrab better but I doubt it makes much of a difference. When I bought the first 2 original Setrab coolers I had to buy them from Earl's ( Setrab WD ) because they would not sell to the public. In fact, Earls did...
