As some of you know I've been chasing the ghost noise in my 07 V2K classic lt.
So I swapped out the motor with another 07. Noise is better (audible) but still the same. But I need some help with a 2nd gear stumble with this new/used motor. 2nd gear moderate to heavy acceleration stumbles at 35 mph everythime. No issues in any other gears. Low easy roll on no issues at all.

I've unplugged the speed sensor to force the ecu into thinking its always in fifth gear, with no results. Did the same with the gear position sensor with no results.

Any ideas...

Hayes, can you give me some details? And how you or your tech determined it to be a bent shift fork?

Thanks for any insite you can offer.. This motor is still under a 60 day used warranty.. So I need to decide if it's an easy fix or it gets pulled and returned..

thanks again,

a stumble or lurching starting as the power goes on and gets worse as revs build is very likely shift fork/rounded drive dogs in gearbox.

Just to be clear. It only stumbles in 2nd doing a hard acceration and always at 35 mph? It's only one quick buck and then its perfect? I can not duplicate this in any other gear or speed. Can this still be a bent shift fork?

This is the problem I had. The mechanic knew as soon as I described. I didn't mind because I had an internet diagnosis from Racnray with the same outcome.

Mine was only once and only in 2nd gear. An ignition miss would be constant because the ignition would keep missing (in my opinion). You can read about it here.

It was a joke. Hollow point bullet.

Good read Mr H, the only thing that had be perplexed was a comment about a hollow point? wtf is it and how would it have helped?

It was a play on troubleshooting and trouble shooting. Like diagnosing (troubleshooting) and shooting with a gun (I was having trouble shooting [with a gun]).
