Pulse in on one lateral even in neutral on T-20

[micmac]

I'm wondering what would cause a pulse on one of the sticks with the (engine running) in neutral. This is on my Max IV and I'm planning on pulling the T-20 and going through it anyhow just looking for some advice as to what to look for. I'm thinking a diamond shifter is dragging on the the shift groove. I know I have some homemade easy shift mod and possibly one side is pushing on the shifter.

It almost sounds like worn drum bearings. If the drum could wobble it would move the bands and therefore the plungers, vibrating the lateral stick. If the input shaft bent I guess it could too but I can't see how that could happen. Keep us posted, hope it's a simple/cheap fix.

Will do. Unfortunatly as you know nothing ever ends up simple or cheap on these machines

Big 5 has a pulse on one lateral, too. My pulse is only when it's moving (it seems), but I'll have to check to see if it's still there in neutral. I figured it must be a worn drum bushing, too. I don't think I've ever had that transmission apart.....

Another piece to the puzzle. The Driven also seems to have a slight wobble to it Hmmm. I hope it's not a bent input shaft.
