I didn't say you shouldn't be worried... 85305 doesn't need to worry just by switching tire sizes... That is not the cause...

You need to get yourself a temp gauge and see what the temps are... Usually that fluid is coming because of a heat issue...

And you are correct, stock e4od's are fairly weak... especially when you throw programmers and tuners at them... What kind of tuner is it?

It is a hypertech, I was talking to a friend of a friend last night, he told me that the front seal in the pump, sits on a brass bushing and the bushing wears out and will start leaking. he said I need to get a pump that has a new seal or get a seal and bushing.

Might also be the Hypercrap, thats known to destroy automatic transmissions:humm:

If it is that, I can't complain much. Its been in the truck almost 10yrs. I am sure it is not that.

Well maybe thats why it's gone thru 2 transmissions lol

Everyone has a right to there opinion. I am sure that is not the cause of the transmission blowing oil out the pump seal.

Just sayin man. Those programmers are KNOWN to toast transmissions. So while I cannot help any further than that, hopefully you figure it out.
