All is fine and dandy on my drive to Arby's on my lunch break. About a 5 minute drive from my place of work. After it get my food and get back in my V i start her up... There is SEVERE knocking for half a second to a second and then it goes away. I listen carefully and drive different ways to try and make it knock again. doesn't do it. THEN almost back to work at a stop light. The light turns green and as I start off it kicks me out of first gear with an array of grinding. Doesn't do it again at any of the following stops.

2006 with 80k. I am hoping the popping out of gear is curable with revshift MM and tranny mount. which will be in order very soon if it acts up again. But the knocking... It's not low on oil... but it does consume probably 1 qt every month and a half or so. Also I'm pretty sure my harmonic balancer is bad. (vibrates according to rpm usually in 5th gear aroung 60 mph) Is it possible a pretty bad pulley could slop around or was this internal.

I do have a pretty solid extended warranty.

Any insight?

Thanks,
Eric

blow the bitch up and get the warranty to cover it.

my guess? you have a collapsing/collapsed lifter that pumps back up and works after a bit.

The knocking on startup sounds like a dual mass clutch with sticking weights. The slipping out of gear, not sure...

Hello ImEpayne,

Have you experienced the knocking concern again? Please keep us updated! I would like to offer you my assistance in working with the dealership if you are willing to take it in. If it happens again and you would like to see if the dealership would be able to diagnose the concern, please private message me your name, contact info, VIN, mileage, and dealership you would like to work with. Thank you very much for your time.

You know, mine has popped out of first gear occasionally in each of two trannies. Keep in mind I've been driving a stick for over forty years and I've never had a problem with this, but I have noticed that occasionally I don't get it completely into first gear at a stoplight, and that's when this occasionally happens. I can't believe I'm missing the gear by not placing the shifter correctly, but that's what happens. Sometimes it's quite a bang when the shift lever pops out of gear and into neutral. I know you won't believe you're doing this -- I didn't believe I was doing it either!! :)
