Is there something wrong with my rebuilt transmission...
... or is there something wrong with me
 I am installing everything back in the car after having the transmission rebuilt with a LSD and along with the 3.6 and new axles. The transmission is mounted to the engine and the engine + transmission is in the car. I know the clutch needs to be adjusted (it is way out), but that is not my current problem. I have the car up on stands and started today to install the new axles. I put the one side in (the other side is still out), and decided to put the transmission in gear so that I could torque the CV bolts - and here is my problem. It is feeling like the transmission is going into gear, but it is not locking up the wheel as I was expecting I know I might be demonstrating that I am not a good mechanic here, but if I put the transmission in gear should it not lock the wheel - even if the other wheel is not attached. I figured it would lock due to the engine?!?

without the shift linkage adjusted, can you be sure the trans is really going into gear?

What about this? It is a LSD. That is, "Limited" slip. This isn't a full locking differential. Some slip is expected. Could that be the case?
Good luck! Larry |

In a Limited slip, the LSD will transfer power to the other wheel when it detects that the main drive wheel is not getting traction. As said above this is not a locked spool.

How about pulling on the emergency brake to lock the rear wheels?

OK, it is not my transmission - it was me not thinking straight and under to much pressure to get the car running...
If you put your car in the air with the wheels off the ground and put the car in gear, you will still be able to turn the wheels - they do not lock. I have no idea why I was expecting them to as I have done this several times before, and should know better. Just having a brain fart moment... All is good and I will continue the work!

I stick a cheapie (aka soft) #2 phillips screwdriver into the vanes of the rear brake rotor and let it bottom out against the brake caliper to torque the CV bolts. That way you don't have to keep messing with the E-brake to turn the axle. Even works for torquing the axle nut.
