I’ve got a 4030 Allison tranny, runs great, parked at home after 200 mile trip, couple hours later saw a small red puddle of Transmission fluid. That was a week ago, try tightening pan bolts. Yesterday was going to move it, while letting air build up, there was a much larger puddle of oil. This is on a2001. Owned probably 25 of these transmissions, first time I’ve had a problem. Any ideas would be greatly appreciated.
Thanks in advance
