gear noise - sm465/np205

[eric67m]

On my 67 K10 LWB, which has a sm465 4speed and a np205 transfer case I recently swapped out my transmission and transfer case because my old transmission output and coupling had lots of slop. I have been driving with the "new" ones and have found a few things that are different than the old set.

1. There seems to be more "gear" noise in 2nd and 3rd than I remember my old transmission having. This noise goes away in 4th.

2. It is often times hard to downshift into 3rd or 2nd. Worse when engine is colder but sometimes when warmed up.

3. I still have a little bit of gear slop noise when I get off of the throttle. I think that this may be in my rear drive shaft (front not installed currently).



I definatly had problem #3 with my old set and that is sooooo much better. Do other people have these problems? I am thinking there is something slightly wrong in the transmission, possibly syncros?
