Bad knock and jerk
 

So, I still have the problem that I posted a while back with the jerky throttle. There is always a jerk and knock when you get back on the throttle. It seems that the RPMs climb a second before the transmission engages and, knock! Depening on the gear, it can jerk really bad. Also lately, Ive been noticing something that seems a lot worse. Truck at dead stop... throttle, 1-10 MPH, Knock/thud/or boom and it feels horrible. It's kind of difficult to describe. This does not always happen, but is starting to happen more than usual. I also noticed that it only seems to do this when I go straight from a stop, or turn left. I do not think I have experienced this while turning right. Truck has 212,xxx miles and the E4OD has been rebuilt within the last year. Any help?
Thanks guys

Who's chip is in it?

Sniper tuning.
But the jerky throttle occurred long before the chip.

Not a good day. Snapped the front u-joint in the rear drive shaft. Got towed home. Went and got a new u-joint and threw the drive shaft back on. Truck doesn't move. I can put it reverse or drive, and it feels like it is going into gear, but will not move. I need help.

Does not move in 2wd or 4wd

Sounds like you broke the center support or the foward drum in the tranny...

Any information I can get those things ? Fixable or do I need a new transmission ? Transfer case ? Thanks CSI

Nothing you can do without pulling the tranny. Its going to have to be torn down to find out what the issue.

Take it to who ever build it for you and have them look at it.

At your HP level there is no reason the tranny should have failed.

After reading your first post... You could have a bad TC... but again, it comes down to you taking it to who built it and getting them to look it over.

Thanks CSI. Did some draining and pulled the pan, no chunks or anything that looks concerning. Just going to have to pull the trans and go from there...

My 460ci gas F250 4wd experienced that jerking thing on a left turn only......ended up being something at the front left drive shaft. Seems to me it would be easier to look there first than pull that tranny. Of course I'm probably out in left field but it was a similar thing with the jerking and all so just thought I'd toss that on the table. :c:
