Make sure the hub, dog keys and expansion springs are OK and installed properly. Do a quick check on the rollers inside the rear of the input shaft, the front bearing surface of the mainshaft, and the mainshaft endplay and rear bearing. You didn't mention which (18 or 23 spline) trans you have and the 18 spline can be normally pretty noisy and cover up an early bearing problem.

18 spline and this thing is giving me headaches.

Got rid of the Lakewood bellhousing, tried the wider brass vs steel shifter forks with different cover plates, installed a brand new shifter, put the older, thicker syncro's in and gained .015" and still had the same problem. Bearing's are fine.

Found out the new expansion rings we were sent were the wrong ones and caused the dog keys to be cocked. Thought the problem was solved. Wrong!

Also tried a new slider, compliments of Brewer, and still have the same problem.

From our local 833 expert's that have stopped by the shop to verify the trans was assembled correctly, all the way to asking Arlan Vandkee's advise, the dog gone transmission is still kicking out of 3rd.

Every part in this transmission is brand spanking new with the exception of the cover plate (tried 3) and tail shaft.
