Got another question today about the front and rear clutch pack plates. I guess I never answered it, something else I forgot. Anyway, there was two types of steel plates and two types of fiber plates. Waved and flat. The wave plates came from the civilian market and where initially used in the...

I was asked a question today about where I get my "new" clutch plates from. The answer is from private collections. "Fatsco" still has some "fiber" plates around but they want almost $10.00 a plate. They cannot get new fiber or steel plates either. So when their stock is gone, it's gone. I have...

...transmission. I've already spent more than $6,000.00 on machining alone, not to mention all the other parts I have bought, like gaskets and clutch plates and seal rings and "O" rings, and the actual transmissions themselves which I've paid up to $400.00 each for, just to mention a few things...

...cooler and "oil" sump. You could not pick a worst place to have a crack in an Automatic transmission. Remember water will destroy fiber clutch plates. Since this has happened to three oil pans, that tells me there is a defect in the casting from the factory. Really no way to fix that. If the...

...302M . The question has always been "why" ? Over time I have found out several things wrong with the 302M unit. The biggest being the front clutch only having three fiber plates instead of the five it has now. I've now found and confirmed another big one. The front "servo" . In the 302M...

...harsh shifts there are other things that can be done to prevent that. By lowering fluid main line pressure your causing lubrication issues, clutch pack apply issues and will end up with a burnt-out transmission. So check your pipes to be sure no one has drilled them to lower fluid pressure.

...be very careful to not damage the sealing rings. Then you will just slide the valve body into the three governor tubes and the reverse clutch tube. Install the four valve body bolts but leave them loose. Using the alignment tool as outlined earlier make your adjustments. Tighten the reverse...

...purchases. This picture was taken "after" I used a "Scotch Bright" pad on it. This is a critical part. The "oil delivery sleeve" holds the clutch housings and provides sealing for the clutches themselves. It must be in good condition. Yes it was in a sealed box and wrapper, but 65 years of...

...like this away ! This center support is ground down, totally useless. Throw away ! You can see how the guide pins are gouged out here. The clutch plates will grab these grooves. Throw away this part ! This rear clutch housing is so severely grooved out there is no way it can be repaired...

...part to machine. They will need to be heat treated afterwards though. With gaskets and oil lip seals and sealing rings still being made, and clutch plates still being made, and bands being relined, all that is needed is a few oil lip seals and some sealing rings made up. We'll see. Here's...

Today I'll show you how to check the "reduction" piston and the "direct clutch" piston. I finally received the new reduction pistons outer oil seals from "Fatsco" . I bought two. They have six left. So, I reassembled the reduction unit (again !) and now I need to check the operation of the...

Here's some pictures of that poor transmission I just tore down. You see that ring in the case ? That was from the front clutch assembly grinding into it. It was almost through the metal. This oil delivery sleeve has the seal ring welded in ! I have never seen such heat related damage ...

...the military mechanics didn't know what to do with an automatic. Plus, it was one less oil the military didn't need to stock up on. If you had ever torn down an automatic transmission that had used 30W oil in it, you would see for yourself the damage it can cause, especially to the clutch plates.

...loss. I have never seen such destruction before ! The main case was even broken !!! Half the bronze thrustwashers where destroyed. The front clutch assembly, destroyed. The input shaft and output shaft destroyed. It was really disturbing looking at all the damage. The one that really gets me...

Well I finally found out what MWO "B" means. MWO "A" means the front clutch has 5 disc's instead of the original 3 the 302M came with, (though the 302M later added a fourth clutch plate, not sure when) . Also the front "servo" was replaced with one having a larger apply piston for more front...

...decided to blow up. After the large reduction piston is installed, install this thrustwasher and the two seal rings. Then comes the "Direct clutch Drum" assembly or High speed clutch. You can install the piston in there before installing it on the transmission if you so desire. It's pretty...

...transmission into a 303M unit. When the first HydraMatics where installed in the M135's they thought they could get away with just using three clutch plates in the front drum assembly ! The "civilian cars" had five clutch plates at this time !!!! What were they thinking !!!! They also...

...pipe as the oil from the reduction unit is not enough to keep the pump operating correctly. Most people do not realize the main cause of clutch failure is lack of oil pressure. Either from leaking or torn oil seals or sealing rings. Yes shift timing is also important as is how much pressure...

...damage). Actually, it was originally a 302M but it was converted in 1964 with the "A" and "B" modifications. Basically, they added two more clutch plates in the front drum assembly, a larger front servo and a few other small fixes. That is all the difference between a 302M and 303M...
