I think this has been covered here before, but what is the best way to seal the tube to the case? I have the engine out right now, so access is good. Thanks! Master, again and still

If it's not clean & dry the ATF just wicks around whatever kind of gasket sealer you use & leaks again. good excuse to ch the fluid/filter & adj the band live every 24 hour block of time like it's your last day on earth

I would be looking at the tube real close to see if it is bent or cracked at the groove also check and make sure that the tube is going in the case deep enough. We install tubes at work on a daily basis with NO sealer and rarely ever have one leak if all is in good shape 70 duster full chassis super pro 416 CNC Indybrock heads 727 w/brake best so far 1.212 60 6.219 in 1/8 at 110.88 9.768 at 137.81 1/4

Even with the dipstick unsupported it wouldn't leak. Later Dodge started using this style seal in their truck transmissions (early/mid 90's)

Other than that, a good clean hole and tube with a fresh o-ring should seal by itself, of a smear of silicon or Right Stuff won't hurt. Free advice and worth every penny...

I once tried to re-ring my tube with one out of an assortment that was about the right size, wouldnt seal. Went to a tranny shop and the guy said it takes an O-ring just the right size. A few thousandths goes a long way. Gave me one and problem went away.

When installed, I cleaned the tranny area, installed with the o-ring and rtv blue sealant. I'd heard from many sources on leaks in this area. Mounted the top of the flexable stainless wrapped tube to firewall. No leaks, looks good and easier to check fluid. A little spendy but to me it was worth it.

A new round one(not from a trans shop though) leaked until I pulled the pan in my post but I remember thinking that the OD should have been larger. live every 24 hour block of time like it's your last day on earth
