I had bad vibrations with my 4 speed and after pulling it out found the bearing retainer to be the wrong one. They have different sizes for different bellhousings. It is just something you could check.
Cant do pics until my computer guru gets back. Would it be possible to switch input shafts from an a-833 to a-833 OD? That chevy spline is to small for the flywheel bearing.
Got this today an thought it would be a good one to replace my a-833 cause this one is an overdrive. What is with this input shaft/ Any help would be appreciated. Thanks Ron K
