Actually I do not - I do know the viscosity is close. Was just throwing a long shot out there just in case there was a chance that an apply component could be turning another component via parasitic drag could be causing my output planets to rotate. But now being informed that is not possible...

Yeah both the end plays were checked and front play checked with the tail shaft preloaded =kept the rear tighter than the front. Tightened up the reaction carrier float with 4 tang washer. If I remember correctly the snap ring for that retainer gets locked into those "humps" on the retainer so...

Well I did install the Sonnax roller front hub kit.... If I move the idle up with a calibrated piece of wood on the throttle to about 1200 ish it sounds like the whine will slowly wind down some and pick up in relation to the steady engine rpm but it may be possible the ecu is varying engine...

Have an 80 that i built about 3000 miles ago with the straight cut gears on the output planet. From day one I have a gear sounding whine when in park or neutral which sounds exactly like the typical 1st gear planetary whine while driving but a much quieter . Noise goes away in R or any fwd...

Did consider the Allison but the 4l80 ( along with the 8.1 vortec ) was literally a bolt in deal- the P30 chassis already had the extra holes drilled in the frame so all I had to do was slide the cross member back and everything lined up, used Summits adjustable trans mount and shorten drive...

Yup that's the one. None of the shafts had any scoring or wear marks on them, a few black shadow "smears" on the 4th and direct/fwd steels but the frictions were all perfect throughout . I probably could or should have left all the bushings "as is" but since they came with the Jakes kit- the...

guess I worded that wrong, I was referring to radial play with just the shaft stuffed into the pump laying sideways. I was just making sure I had no binding of the bushings and noticed there is a slight bit of play on the big end vs the stator support tube. I am using the thinnest select I had...

I have .007 " 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 with the pump and overrun/...

copy Building with Jakes stage 2 kit and his B82 low stall diesel converter built to gas specs behind an 8.1 in a 13k pound motor home and will be seeing mostly mountain roads Any suggestions what to drill the bleeds out to ?

Have been building up my motor home 4l80 ( 1995 unit) I got from an RV salvage yard and found no cushion plate in the intermediate. I cannibalized a wave plate from the old 475 and used a .100 and .097 - ish steels to get .043 on the stack and found this post. The intermediate feed orifice - it...
