Cj Ford RTS Transmission Vibration

Hey guys, haven't been around for a couple years but I'm going home soon and I'd like to fix up the Death Machine for a couple weeks of fun. It's been sitting for almost 2 years.

So, when I parked it I had just installed an all new drivetrain, freshly rebuilt 258, refurbished Ford RTS toploader transmission and rebuilt transfer case with 3.15 low range gears. This setup had only 800 miles on it when parked, and it ran like a dream with one problem. When in 4th gear (overdrive) there was a pulsating vibration coming from the drivetrain. It only happens in this gear, regardless of speed, so I assume it's a transmission problem. This is an oddball transmission, hopefully someone else out there has had a similar setup.

Since the power flow goes through the input shaft down down to the counter shaft, then back up through the OD gear on the output shaft, you will want to look at the counter shaft bearings, input pocket bearings, as well as the two gears themselves.


The transmission is actually relatively simple and is the same basic structure as the T176/77 found in Jeeps.

Paperwork will ruin any military force.

That's good to know. I never inspected this transmission, I bought it "refurbished" from an online vendor. He also sold me the T-case rebuild kit and the Advanced Adapters kit to mate the two gearboxes together. Both of those kits had incorrect or missing parts that I had to track down later, so I wouldn't be surprised if the transmission was faulty to begin with.
