Thump/click only when going from 2-3rd when shifting?

[robertk]

So about 90% of the time I get a distingtive click thats almost a thump during normal driving with a 2007 6.0 5sp 4x4. I hear it and can feel it on the floor board on the driverside.

sometimes I think I get the same thump/click when I first start it.

Make sence? Any idea's? the 2nd to 3rd shift is what bugs me and concerns me...

Ive got the same thump/click when shifting from 2-3 in my truck. I bought the truck used 2 years ago and it has done it since ive owned it.

Mine just started this too, any ideas?

I assume you are referring to Torqshift tranny? First things i would check are the engine and trans mounts. Then check the turbo down pipe and make sure it's not binding against the firewall. Check u-joints, and cardan joint, if you have one. Check body mounts.

My downpipe is hitting the firewall..Thanks

cool, that is pretty common, especially if you have aftermarket (larger) downpipe.

My truck does the same thing. I have factory exhaust too. Any ideas from anyone? Its a little concerning.

Thanks

just because it's factory pipe, does not mean it's aligned properly. Sometimes the factory ones can be put back in wrong. Does not hurt to check. Also check your mounts, and driveline.

My '07 does this too. I seem to notice it more when it's in 4x4. There is a TSB on this:
Intermittent Clunk from TorqShift Transmission:
Trucks equiped with the TorqShift may exhibit a clunk when shifting from drive or reverse to park, from reverse to drive, and/or at the 2-3 upshift. If these conditions are intermittent, it is normal play/backlash in the drivetrain. Broadcast Message 7028, 0215.
