M1165 Won’t Accelerate, Feels Like It’s Slipping

[65grendel]

Took my M1165 for its first drive today, didn’t go well. I couldn’t get it past about 10 mph, if I gave it more gas it would feel like it was slipping, didn’t feel like it actually accelerated. Transmission didn’t try to shift or anything. Any ideas what could be going on and what I should check?

Did you try high lock on the transfer case? Sometimes these have CV axle problems that resemble slipping.

Any inspections prior to driving? Fluid levels checked? Visual inspections via a creeper underneath?

I did not, was on the street so I didn’t want to leave it locked, I don’t know how fragile these things are. Safe to test for a short distance?

yes, all good, no leaks or anything either.
