    where on the tranny pan is it leaking? What year and what engine? I am guessing that it is four wheel drive because the vacum lines you are seeing go to the transfer case to shift the front axle in to gear.Did you use RTV on the gasket. How did you blow your pan seal?

    is it near the front pan on the passanger side? When you changed the gasket did you check for gouges or cracks in the tranny and bent pan or sealing surface? Did you change the filter either of the times if so did you make sure that you got the old filter top seal out it is a common problem for these to get stuck in the pump. Is it leaking bad enough so you can not drive it or is it just a small leak?

    i just went out and im thinking a problem is because its new fluid its kinda hard to see on the dipstick i think we over filled it cause we put and extra quart in and about that much came out....yes i changed the filter both times put new ones in just in case and both olds the rings came with them...thanks does the overfilling part sound right???

    over filling should not cause it to leak there that area is normally covered in fluid. If you over filled it you need to get the extra fluid out because if it is to full the fluid can be caused to foam up causing damage to the tranny. Also check the seal on your dipstick base that could be leaking and throwing you off

    IFS lifts are really expensive for 5 inches it is about 1500 dollars for the kit. To install the kit requries cutting off frame brackets and welding in new ones. If you are only looking for a few inches do a body lift about $80. you can also crank you torsen bars for about two inches with a add a leaf in the rear. If you are looking for large tires yor best bet would be a SFA conversion

    a sfa swap would take a good amount of time. But it is a lot stronger then the crap IFS. The best axles to use wouold be out of a jeep because they are narrower then the full size axle. With the jeep axle the transfer case dose not need to be changed. You would have to fab up sprong mounts and put together a set of front springs. The steering box also bolts up to the steering on the jeep axles. I would figure on a few weeks for the swap working on it part time. The more parts that you have gattered at the start the faster that it will go. I would do a good amount of research before you dive in to it and figure out what your goals are

    I have some questions about your leak problem.

    Did you straighten the pan surface?
    Were all surfaces clean to the metal?
    Did you use just silicone?
    Did you let the silicone set up fairly firm before installing the pan?
    Did you use the cork gasket and silicone?

    The reason I as is:
    If you dont let the silicone firm up before the install it will squeeze out and cause a leak.

    If you used a gasket with the silicone the gasket will squirm and again leak.

    The torque on the trany pan bolt is around 12 lbs. (I think). It does not feel tight at all and the urge to give it that one more turn is hard to resist.

    On all points I can say "Been there done that"
