Here's an easy one for you tranny guys. I have a 99 Z71 with the 5.3L and
4L60E. I've been through the rpo's and can't find the option for the deep transmission pan. How do I find out? My pan is about an inch and a half, but I haven't crawled under there to measure exactly yet. Is there a P/N or something to verify which is what?In the old days, they didn't have a drain, so they fixed that. Now you have to disassemble stuff to get to the pan bolts. GM sure has some wizards working there.
