The mean 700r4

[83_c10]

Alright I've had this truck for 5 years going on 6 and since I have owned it it has leaked. I just replaced the gasket and filter in the trans. It didn't leak til today. It got really cold last night and I think the gasket shrunk enough to let fluid piss out. I am thinking the pan is junk. I could straighten out the rails on the pan but that would weaken it more. And it would just bend right back as soon as you torque it back on. I torqued the pan on to 10ft. The front and rear seals have been replaced too and since being replaced they haven't leaked at all. Just that damn pan. So I am wonder what else could possible cause the leak. The lines that go to the trans cooler aren't leaking either. Would it be a hairline crack? Also when I am driving this truck on the highway as soon as I hit overdrive it falls flat on its face. Zero power. Zero response. I have to drop it back down to get up to speed. Even when I get to speed and put it in overdrive she just doesn't have any power at all. It's like it just got hooked up to a train and is having a hard time towing it.

Get a good pan gasket, the rubber one with the built in spacers that wont overtighten the gasket, no matter what, straighten out the rails first though.

Give that enjun a good tuneup then, make sure the cable is properly adjusted to the trans.

You may have overtightened it. It's not hard to do, especially with cork/rubber gaskets. If you didn't overtighten it to the point of dimpling the bolt holes, you can start over with a better gasket as suggested. For trans builds, I use an INCH LB torque wrench for this reason.
