[FC] More ? for the masters; 90 weight leak

[Paul Steinberg]

The transmission and the differantial share the gear lube, so one side or the other is going to be low.  I wouldn't be too quick to believe that the fluid level isn't going down in both reservoirs.  I would suggest that you attend to this immediately before the transmission or differantial overheats and there is permanent damage.  If the differantial locks up while you are driving, the damage to the vehicle can be catastrophic.  I know, because in 1963 the dealer replace the synchronizers in my Spyders transmission and they forgot to make sure that both reservoirs were full.  After about 200 miles of driving the differantial locked up and the axle sheared in half.  The transmission and differantial were both beyond repair.  Sure glad that it had a 12 month 12,000 mile warranty that paid for the replacement of both.

  Before I randomly start "fixing" things, I need to get someone's two cents 
  worth of info. I have a gear oil leak that appears to be between the 
  differential and the clutch (4 speed mated to former powerglide motor). It seams to be 
  from the lower half or bottom of the connection. I'm under the impression that 
  the differential is a "bath-tub" with no way for the 90 weight to reach a 
  joint. Also, possibly related, after the truck gets hot, when going up a steep hill 
  or accelerating fast, the motor will race and the speed decreases or stays 
  the same (like an automatic thats slipping). Other symptoms: hole plug above 
  clutch cable inlet is missing; there is small amount of oil in the clutch inlet; 
  no 90 weight leaks from filler bolt or top plate; no dripping until it's 
  warmed up, stops after a few minutes when parked, but really comes out when first 
  parked (18" round puddle). I need to get someone to watch it, because I don't 
  know if it's only dripping when I depress the clutch, or all the time. At the 
  rate it comes out, I would think the differential would be dry, and that there 
  would be a trail going down the street, but there is still oil left (but 
  less), and the only noticeable drips are where I parallel park. Any suggestions?
