Idle in neutral with the clutch out it makes a little rattle. Is that the front bearing making that? Should I worry about it ? What a pain in the butt to pull it all back out. Or am I worrying about this for nothing? This is the first 4 speed I’ve ever swapped, mich less driven. So I don’t know what’s normal and what’s not. 90 weight Castro gear lube about 1/2” below the fill hole. Lube was a little foamy so I dropped the level from the fill hole to 1/2” below it. Thanks all.


Some gear noise is normal, although mostly with an 18 spline. I can't remember much noise with a 23 spline???? I don't think it's anything to worry about. If it is something going bad, it will probably get louder over time. Then you will have to pull the trans.


4 speed street legal. Best time 10.99 @ 124 mph on 93 octane pump gas @ 3926# total weight
