Auto Trans Symptoms

Just wanted to know if this is the start of something or nothing to worry about... When I let out of the brake, and the truck starts to roll forward there is a bump... almost feels like the gear is "engaging." I always wait a sec or two before I get on the gas....feels like she likes that more, as opposed to just peggin' it off the light.

Is this the start of a problem....will it get worse?

Could be a U joint, carrier bearing, but probably the slip yoke. It comes from factory with no grease and is non greaseable. I drilled and tapped mine and it fixed the clunk.

Could be a ball joint as well. Sounds like what mine did when it went bad. Can you feel it through the brake peddle? If so, jack the front up and wiggle the tires with one hand on top and the other on the bottom. If it has an extreme amount of play, joints are bad!

Hm... I not sure on this one. I'm not a good drive train guy... sounds more like the "250 clunk" that jesilvas is talking about. I've read a lot of guys on here complaining about the same thing. Pretty sure if I got anywhere close to my slip yoke with a drill my truck would run away from me I've got a guy here in Charleston that works solely with diesels ... I'm sure he's done this to a couple of trucks... if not, you would happen to have a link to a sticky thread on here about how to drill the slip yoke, would you?

Oh it's not hard, trust me.
I hate carrier bearings
That shows the splines, how they aren't greased.
