I know my burb has it. but this question is for my sister. She knows nothing about cars, but she needs a truck and is looking at a lot of older Chevys. I've been told that the 4L60 had a lot of problems and should be avoided, especially since she'll be doing a lot of towing. She's looking at a 95 Sierra 5.7 right now- I told her to check for those numbers on the door sticker, and then to crawl under the engine area and look up to see if there's a big silver pan with "4L80" on it. She says she sees nothing like that. Now she's really unfamiliar with cars, so she may just not really understand what she's looking at (been there). Did they ever stop stamping it on the pans? Is it anywhere else on the truck? I can't tell her to just look at the casing or wiring, she wouldn't know the difference. And, side question, is the 4L60 really all that bad? I've heard that from several mechanics, including one that worked at a couple different Chevy dealers, but I don't know much they really know- they're just acquiantances.
