Steve, Thank you again! This one is not a ‘split nut’. It is, as you described, a round nut with two flats on it, which are 8mm apart. I am assuming that you meant that tightening it would increase (widen) the vacuum span. Please tell me if I misinterpreted your reply.

The other thing that I would love your opinion of is the possible (temporary & Mickey Mouse) cure for the seals in the clutch pack. If I were to use a product such as ‘Trans X’ to soften the seals for a more effective hydraulic seal, is this one of those cases where the cure is worse than the disease? My thoughts are that IF the clutch pack is taking too much abuse in the form of slippage (although there is no sign of flaring, at least yet) what would be the lesser of two evils?

1. Allow the clutch pack to continue as it currently is (no “rebuild in a can”), and play with the vacuum span, control pressure, etc., etc. I have set the vacuum modulator to spec with gauges, so I am prone to leaving it alone, or at best, a very minor adjustment.

2. Use some “rebuild in a can” to soften the seals, and possibly even reduce leakage at the front pump seal as a bonus. The concern is that I have read in the past about these products making the seals leak even *worse* at a later date due to the softening agents.

Another alternative is to use the “crud” & drive around for maybe a couple hundred miles, then draining & replacing the fluid so that the seals are not *constantly* exposed to the softening agent, but perhaps long enough to do what’s needed.

I do recognize that I will need to rebuild the trans in the (near?) future; I am just trying to put it off until absolutely necessary.

Any thoughts on this? Once again, I really appreciate your help!

Thanks Again!
