Hopping when put in gear

[ylwchev]

The problem I am having is not consistent, it only happens once or twice every few weeks. When I put the truck in drive and barely tap the gas to start creeping, the truck begins hopping for just a couple of seconds. I can usually stop and put it in reverse and get the same effect for a couple of seconds as well. It almost feels like i'm dragging something.

Any thoughts?

In that case , I would review the condition of your transmision fluid and filter. If they are old ,changing viscosity,or plugged. It can affect the performance of your transmission oil pump and the functioning of your transmission valve plungers.
As your talking light acceleration hopping i dont suspect the torque convertor ...unless its radically empty.

is the truck long bed? if it has two piece driveshaft it may need the carrier bearing shimmed.

sorry. just looked at your profile and see short box. don't know what is wrong with it.

I've heard that, as well as pulling the drive shaft apart and re-greasing the splines. I do get a random knock in the floor board when i put in in drive from time to time. Next project!!
