I once thought the 5LM60 was '88-'91 (RPO MG5) but we recently picked up a '92 C1500 that also has this transmission.
Aren't the cases different? Aside from the tailshaft, this '92's transmission looks just like my '89's.My 94 was born with the 5LM60/NV3500. According to the only transmission guy I trust, he said they’re the same with only very few differences between them. I do know that my RPO code was MG5. However, after destroying three of them, I had to step up my game to the NV4500, which has two RPO options one being MT8.

I definitely know what one of those looks like, had the provisions for a PTO & such, big honker by comparison.
Both of our transmissions exhibit some sort of growling when getting into the throttle harder below 1,100 rpm or so, hers less so than mine. Sounds typical of the front bearing failure they say the 5LM60 or somethingsomething290 is prone to. I've put over 15,000 miles on mine like this though so I'm not worried, least not any more haha.
