4L80 front end clearances
I have .005 " rear play, am using the sonnax roller front hub and with the .057 pump shim, fwd end play was .012, I sanded it down to .055" and now have about .017" which i am happy with ( trans sitting on output shaft on the ground) .
While checking stator bushing fit I saw how close the overrun was to the pump and measured .011" from the overrun to the pump machined surfaces - is this something to worry about and should I go with the .072" select and try to get my clearance elsewhere ?
Also can you double up pump to case gaskets to pick up some slight clearances ?
Pump stator bushing play - I installed the Sonnax wide bush and clearanced it so the shaft slides smoothly with no binding or marks while rotating the shaft- Is this what we are looking for ?
Also the shaft has slight noticeable play on the rear pump bushing and I understand those bushings do not require any line fitting like the stator support ?
