J2000 Transmission Noise

Finally got around to getting my '73 J2000 drivable, only to discover a loud hollering noise coming from my transmission or t-case. It only happens above around 35 mph and when the transmission is freewheeling. Any load accelerating or decelerating causes the noise to stop. Does anyone have any similar problems with these 3 speeds trannys? Any information on this would be greatly appreciated.

It's the three speed manual. I guess it's a bearing going out, but I'm not sure.

I built the exhaust on it, so no cats. I'm fairly certain it's in the transmission or transfer case.

Sounds like you need to drail the oil on one gearbox at a time and check for metallic residue in the oil. I'd start with the transmission. You can also remove the shifter tower and look inside to see if anything glaring sticks out.

A '73 wouldn't have ever had a catalytic convertor.

Thanks. I'll start with that and see where it gets me. I've been toying with the idea of a 5 speed conversion anyway, so if the trans is shot it'll help my decision a lot. I'll post the results after I check it out. Probably won't have time until this weekend. Thanks for the advice.

Drained the transmission and transfer case oil. Didn't notice anything significant with the oil, no metal shavings other than obvious wear from forty years of use. Refilled it with 75-W90 and some Lucas. Took it for a ride and the noise is still there. Thinking very seriously about a fuel injected 4.0 and AX15 conversion
