can anyone tell me what to do? I have an allison HT750 trans on my recently purchased coach, it has been sitting for about four months I started it to take it downtown for a diesel emmissions test and after driving about a block the engine suddenly killed at the bottom of a steep hill, it restarted fine and went up the hill, but at the next stop sign it was surging while idleing and when I went to go it acted like it was trying to go into direct lock-up. I can not manually shift it into 1-low. it just acts like it is in second, it seemed to work great once it got up to speed, but it worked alot better if I manually shifted up through the gears, taking off from a stop it goes into direct lockup and kills the engine(I'm sure thats what happened on the hill)
I checked the trans level it was low(I KNOW I'M SORE FROM KICKING MYSELF... WHAT A DUMBA--!!!) I added 6 quarts to bring it up to level, but with a 33 quart system, Could that cause all my problems or do I have sticking valves from setting dormant?
Any suggetions would be helpfull, I'm sick to my stomach, kind of like finding half a worm in an apple you're eating. |

6 quarts will do that. On the other end, overfilling by 2 quarts will cause overheating. Keep it between the marks and only check it when it is HOT. Not just idling in the yard, but after an hour or two of highway speed. The fluid expands a lot with heat and must be checked HOT for an accurate reading.

Jim is right, and when you get that far, use a file and cut a mark on the dipstick after it cools off , then the next time you check it cold you will know where it should be on the stick, compared to the factory "hot" marks. Cheers...JJ |
