I had a friend rebuilding his C4 in his 69. He brought it in to the rebuild shop to have it finished. on the weekend he went to the track with it. On his first run the transmission lost every gear accept 4th. he drove it back to the shop that rebuilt it and it turns out they filled it with motor oil! there excuse was "that's what the books called for".
Where did he take the transmission to jiffy lube? What kind of transmission shop doesnt know that you dont put motor oil in a transmission. IDIOTS. I think they need to again.
dumb muthafuc*in shop.....i think they need the sh*t knocked outta them....who puts engine oil in the tranny??....its called engine oil for a reason its made for the ENGINE!!!....i wanna know the name of this place im never takin mine there

This doesn't sound right at all. I don't see a shop that specializes in tranny's putting in motor oil. Secondly, how does a C4 in a 69 Mustang have a 4th gear? Did he put a newer tranny in for the overdrive? This story doesn't add up to me!
Oh ok, at least 2nd gear was left instead of 1st, it would of been a pain in the ass to get home. I can't imagine a shop putting in motor oil in an automatic tranny. Crazy!
i still dont see how even putting motor oil in it would of caused it to fail that catastrophically. also many manual transmissions use standard 10w-30 engine oil so its not like its crazy to put it in a tranny. they simply were retarded by putting it into an auto transmission
