My intl shakes in third gear

[gorman]

I have a 2000 intl with a road ranger six speed. I just had the tranny rebuilt and the clutch replaced and it still shakes in third gear when pulling a load.

I took it back and the shop said it is an engine issue and not the drivetrain.

Any ideas folks?

Very well could be an engine problem. I had something just like that happen to one of my Dodge/Cummins diesel flatbeds a few years back. It had to do with the engine starving for fuel. However, it felt like a shimmy or bad U joint.

take it to another shop for an opinion. Not sure about transmission but if 3rd is on the main shaft and 4th is on a counter shaft, you might feel vibrations like a bad U joint in 3rd but not 4th.

Just a thought not knowing that truck in particular. Does it shake in third gear or is it shaking at a certain speed? Maybe the driveshaft is not back in right if that is possible on that truck?

It shakes until the tach gets to about 1600. Much more noticeable when pulling a load

Well maybe the driveshaft isnt set in the right position ?

sounds like a bad u joint or a bad carrier bearing for the drive shaft

Finally got this sorted out after 2 mechanics wanted me to replace all the injectors. I did a job for a heavy equipment mechanic who knew immediately that it wasn't the engine. It was a bad u joint, a bad carrier bearing, but most importantly it started with the yokes for the driveshaft were installed off-kilter so it threw everything off and caused some damage. Joe got it most right.
