I noticed, yesterday a small puddle of tranny fluid just in front of the right tire, I noticed it once before, but it stopped, does anyone have a clue where this is coming from, Thanks:rolleyes:

Only thing I can think of up on that side would be cooler lines. They run along the engine on the right side up to the transmission cooler in the radiator then up front to the cooler out front.

There's a lot of info on the tranny lines on here, and you'll start to see alot more as it gets cold...very common on these trucks...I was getting a few drops at the end of last year and nothing over the summer, but it's time to think about it again. Problem is, last I knew (earlier this year) the GM replacements will eventually leak too. Anyone know if they (not holding my breath) correct this yet? Warranty end is very near for me, I'm guessing I'll need them changed out this winter. And finally get a tuner....

that is exactly when I have noticed the leaks, when cooler weather moves in, any idea's what part needs replacing?

The two steel tranny lines running to the tranny cooler, theey leak at the ends where the lousy crimps are.
