well please tell what you ment by smoother, cause thats just a word you used to describe what? smoother clutch engagment? or what?

 

Yes

 

If you run to redline in first and then let off the gas you will get a louder thump than if you do a fast shift to second and keep everything loaded. The rear diff assy seems to be moving around because of the change in loading, and the greater the change, the more movement, the more thump.

 

Try this, When shifted out of first, and going into second, give it more gas than you usually do before letting the clutch back up.

 

this only has happened to me on a few occasions when i was shifting fast but lazy it IS driver error youre letting the clutch out to fast
be smoother

 

happens to me when i'm driving very animated, lets call it, hahahhaha.

 

Yea I get it once in a while

 

i sell them...

 

Ya its normal, a good rule of thumb is when you're shifting between gears (especially 1st to 2nd) wait until your body weight shifts from being pushed back into your seat to forward toward your steering wheel and engage the clutch at that point.

 

I get the "thump" if I let the clutch out too fast when shifting from first to second.
