Check the governors driven and drive gear for any damage and debris. Something failed to cause that damage. You have to remove the rear valve body to clean the governor’s screens, they must be loaded with metal, also inspect the rear pump check valve it has been know to come apart and cause damage to the governor gears. Can you post a picture of the governor? I am updating my website I have tons of pictures.rear valve body




The governor is matched to the engine size, tire size and differential ratio. When you call give them the ink stamp number on the governor to insure you get the right one

hey that might be my problem. i had broken gear of the governer. i just replaced that and ever since everything looks good. i could not find anything else wrong. can you guide me how to check what caused that ? i mean how do i know where check valve and or anything else that might have caused it? or what might be wrong with them??

i need help removing my governor (1986 300e 722.320 transmission) i removed the cover on the drivers side and the microfiche shows that there is a nut on the passenger side that needs to be loosened then the shaft turned with a screwdriver. only problem---i cant find it another manual i found online shows a retaining clip but that is for a later model vehicle. did you have the pan off the tranny when you removed the governer what did it take can you help also i am hoping that somewhere somehow there exists a better service manual for my transmission than these 2nd hand microfiche i bought they are a nightmare if anyone knows of anything print electronic whatever i need it MIKE

what i did was i went to dealership and confused them really good , i said i am looking for a governer part. then they printed out exploded diagram and gave it to me.

The release for the governor is on the rear pump; look at page 50, fig. 42 of your link. They call it the axial retainer nut. Remove the 10mm nut and turn the screw CCW to release the governor, turn it CW when you install it, the slot in the screw should be in a horizontal position; locked.

First of all, thanks to everyone who has given advice here.

My car's current status is as follows: I removed the governor to find that all is in order - springs are intact and the valve is moving in it's bore correctly. Gave it a good clean and replaced. Then I drained the oil and dropped the pan to remove the valve body. Split it on the workbench and found quite a bit of 'paste' in the 'oil channels' and on the plate. Stripped the valve body down to the last spring and valve, cleaned everything, blew it all out and re-assembled carefully. This took about 7 hours! Replaced the valve body in the tranny, closed up and re-filled with Castrol Transmax M as per the MB approved list.

Took the car for a test drive and found the following: Tranny shifts out of 2nd, but hangs in neutral - won't shift into 3rd! (this car starts out in 2nd). I then forced a 1st gear start and it shifts to 2nd beautifully and shifts at low speed if I give little throttle, higher speed if I give more throttle. Holds onto 2nd for long if I give lots of throttle, shifts out of 2nd, but won't shift into 3rd.

So it seems as if my original problem of stacked shifts is sorted out and this I put down to blocked channels in the valve body. But what could now be causing the 2nd to 3rd shift problem? Do I need the K1 spring kit as mentioned before? Anyone have any advice please?

i would highly recomend doing a pressure test and getting the atsg service manual for your tranny
