You gotta love it!

RE: Re: brittle gaskets Well I was fibbing, after a closer look at the seals, Im missing a seal, it looks like its inner clutch reduction piston seal. in this case it's the least used seal, used when you are in low, usually not in low for a long time. These seals with a little cleaning usually...

Re: brittle gaskets Please do, document everything, and take notes, take pictures, and take a video if you can, the more information you can give the better the project. Also it sounds like you know what you are doing and you have a good grasp on it, good job! butch atkins, this is not aimed...

Re: GMC Hydromatic You're right Karl, The front oil pump as a whole unit is no longer available. I don't know if they still have parts for that. Back in 1999 I also ordered two transmission kits that also had the oil pan gasket and other gaskets dry rotted from age. Since the gaskets were...

transmission seals Well here is all the basic seals you will need to rebuild a transmission. Memphis Equipment will build this kit for you if you tell them its for a complete rebuild. All of these seals and gaskets for $135.00, not a bad price.

Planetary Gears Now since we have covered the basics on the basic operation, I feel I did not cover the planetary Gear Units very well, so we will look a typical Planetary Gear Unit. Even though the basic shape will very slightly, the operation will stay same. Remember Band Tight – Reduction...

reduction section In HIGH RANGE the pistons activate and lock the Planetary Gear Unit as one with the planetary Gears of the Reduction Shaft. Everything is turning at the same rate as the transmission Output Shaft

reduction Reduction Operation Again we are working with a Planetary Gear Unit. The reduction gear section Planetary Gear Unit is more massive in construction than in the transmission side also instead of using a band to hold the drum for reduction, the reduction section uses a Forcing Piston...

You’re Welcome, When I got my M211s, 1 good truck, 3 only good for parts, I knew absolutely nothing about a M211, I didn’t even know how to start it, much less drive it. I got my learning experience through the Fire Department. (All Trial and Error). Working on the fire department truck along...

You know I forgot to show you guys reverse. I’ll add a picture later because I have to play choo-choo but, when you select reverse here is what happens; As you see in Reverse, everything the same for 1st gear except the Rear Planetary unit is in Neutral - Band off and Clutch Off. The Rear...

correction In the photo if the transmission drive-line, I mentioned that there were 6 clutch plates in the rear Planetary Gear unit, Well again my typing skills come through again. In the front planetary unit there are 5 floating clutch plates with 4 stators In the rear Planetary Unit there...

4th Gear Drawing. The easiest to understand, since the Front and Rear Planetary Units are in (direct Drive) Everything is spinning at engine RPMs (no reduction) 1 to 1 ratio

3rd Gear Drawing. We know in this gear the Front Planetary Unit Band is TIGHT (reduction) and the rear Planetary Unit Clutch is ON (Direct Drive). The only reduction in this case is from the Front Planetary Unit. Now when we go from 2nd to 3rd, we asissit the torus halves and the transmission...

2nd Gear Drawing. As we can see the First Planetary Clutch is in Direct Drive, The whole unit is turning as one. Which means if you follow the color GREEN, the Main Shaft, both Torus Halves and the Driven Torus Shaft are all spinning at engine RPM. We already know by now the Rear Unit Band is...

Note, automatic transmissions do not change gears as manual transmissions; all the planetary gears are always connected to the same components and are never disconnected. The operation that is happening in the transmission are: bands tightens or releasing, OR the clutch pistons are activated or...

Cutaway views of transmission What I’m going to talk about next is just the basic shift pattern, I’m not going into detail about throttle settings, control valve setting or reduction gear operation HI / LOW. This is only going to cover the transmission from 1st to 4th. The Players Flywheel /...

The reduction gear section

The transmission is upside down.

transmission Well a little TLC, it does look too bad for sitting in boxes 9 years, waiting for the parts from Memphis Equipment. this is what the transmission looks like when you remove the drain pan, access cover to the valve body, and reduction gear housing. I'm still getting all my notes...
