Loose trany gear - clunk when I start

I hear a clunk when I accelerate and think it has something to do with the transmission. I want to know if it is something that can be fixed.
--For starters, it is not due to bad CV joints, both axels were replaced last month.--
The car is a 95, VTEC, manual, stock except CAI, 190k. I have recently done a lot of work on the front suspension: New upper control arms, upper ball joints, radius arm bushings, sway bar bushings, inner and outer tie rods, both axels, all 4 brake calipers, rotors, pads.
It is like this: I press the gas moderately aggressively, the engine revs, then the car abruptly pulls. There is a slight delay between giving gas and the actual vehicle acceleration. When the acceleration comes, the steering wheel jerks. It feels like something is slipping than suddenly catches.
I took off the right front wheel and can see that everything from the trany out can rotate about 1/8 of a turn before something catches in the transmission to stop the rotation.
Do you know how much rotational play I should expect in the Transmission or what would cause the play.
I will not rule out the axels causing the noise. They are brand new, but may have been defective. The lower ball joint has not been replaced, so the issue may be there as well.

Please let me know your thoughts.

Ben

Re: Loose trany gear - clunk when I start

you should check all the mounts and the hanger bearing witch is the longest of the axle connected to the block with three 14mm or 12mm bolts ,make sure when you got the axle done they gave you the abs ring on the axle .Keep posting updates.

Re: Loose trany gear - clunk when I start

I wish I could blame the dope that installed the axles, but that dope was me.

It was finally warm and dry enough to jack the car up and look closer. I confirmed that the 'slack' in entirely in the transmission.
- no play in inside or outside joint either axle
- hanger bearing secure

to reiterate the problem - the wheels can rotate several degrees before catching

OR

The engine/trany can spin a little before something catches in the trany and the wheels turn. (it feels like chain drive motorcycle where the sprocket can turn a little before the wheel catches because of chain slack)

I do not think that this behavior is normal, but I don't know how to diagnose trany issues.

I'm the 3rd owner, purchased in May09. Owner #2 replaced the clutch and blocking rings and 2 syncros in Mar09.

Engine: H22A1
Transmission: M2F4

Re: Loose trany gear - clunk when I start

I saw another thread that said a bad mount will cause this problem.
But,
I can make the clunk with just my hand turning the wheel when the car is jacked up.
