Why did you replace the transmission? And what is the known condition of the
replacement transmission. Was it a "good used" unit? Rebuilt unit? Dave is
on to something with regard to the lay shaft. It may also be a universal
joint that acts up under acceleration but does not when no load is on it.
Doesn't explain no noise in 1st however.
As a group we need more information as to the reasons for the transmission
replacement and the condition of the replacement.

Occurrs in 2nd, 3rd and 4th, only while accelerating or at a constant
RPM - does not occur on deceleration or when not under load.

Are you sure it is coming from the engine? I had a similar issue which
turned out to be the transmission. The 'under load' part seems to point
in that direction. Also since it started after the transmission
installation...

Is there a difference in different gears? Does it go away in fourth?
If so it is layshaft related. BTDT.
