If you are to remove the transmission to replace the B3 friction disks, you MUST reseal the front pump, period. You do not want to remove the transmission again to replace $5 worth of seals. They all leak sooner or later and it makes a huge mess when they let go.

If the car has no issues going forward, just do the B3 bands and the front pump seals and leave it alone!! If your mechanic wants to do a full rebuild, decline or take it elsewhere. These transmissions are very tough other than reverse and leaks.

Also take the opportunity and visually check the kickdown solenoid for hairline cracks. Again, common issue eventually. There was an updated part later.

PS: Don't change the oil, or you'll almost certainly lose it completely. Get it rebuilt as soon as you can.
