    I think my tranny pan is warped because I have changed the gasket and fluid twice and it has leaked from the back of the tranny pan ever since. I even tourqued the bolts down to proper specs. I am considering a deep pan possibly one with a drain plug. This is what I have found so far:

    B&M deep tranny pan

    Although I am not a fan of the chrome, I could deal with it for the extra capacity and drain plug. Do you guys know of any other options for a deep tranny pan? Also, which is better aluminum or steel?

    Thanks guys

    I have one of those B&M's...its in my garage because the exhaust crossover pipe was too high, and the pan wouldn't clear the filter when putting it on, had to pry on the exhaust pipe a lot. If you have a different exhaust setup it would work fine though, i'd sell you mine if you want

    I run the TCI aluminum deep pan. I bought it used from here. The fins have been slightly ground in the front to clear the factory crossmember.

    For aluminum vs. steel, first off you couldn't grind the fins for better clearance on a steel/chrome one! Second, aluminum will cool and dissipate heat better than a steel one. The aluminum is also much thicker than the steel one. However, steel is stronger and would stand up to beign bashed on the trail more than an aluminum one. I carry my original pan as a spare off-road in case I put something through the aluminum pan.

    Steel is more forgiving, steel will dent..... aluminum in most cases will just crack or a chunk will pop out of it. In a 4X4 I'd stick with steel.... but then again I'm not smart enought to carry another pan and fluid to replace it if I break it.

    I bought mine off ebay for like $20. steel pan with a drain plug. Its been of twice, and still no leaks. I think it was a B&amp;M pan.

    Have any of you guys had clearance problems with a deep tranny pan and the stock exhaust? I know 90k5 did but I looked under my truck today and it looks like the exhaust is low enough to not interfere with a deeper tranny pan.

    Thanks for the input thus far.

    Bubba have you had any experience with those pans?

    Thanks
    Ross
