OK,

bought another car with a transmission issue. I have two in the garage that I had planned to fix and now is the time I guess. One had about 79K on the clock and good looking clutch plates, the other has about $130 and the plates are still good, but more worn than the other. My plan is to replace the A drum with a reinforced one along with the valve on the other and keep it for a quick swap if any of mine go bad.

I ordered a reinforced A drum and the pressure valve upgrade- has anyone done this? Can I just remove the part of the valve body that has the valve, or do I need to remove the whole valve body to replace?

Thanks!

 

Just the forward valve body. With the valve body on the bench I used a couple of bar clamps to hold the cover plate in place while removing the screws. The same to reassemble.

 

Good news- The A drum fractured but never broke on the trans that was in the car so.... Looks like a straight forward swap, valve and install! I'll rebuild one of the others bottom up so I have a good used spare.

 

To wrap this up- I replaced the valve and A drum, filled it at 30 degrees C and it is running like a top- took it around the block and on the freeway.

Interesting thing though- it is very tame in regular but in sport the car turns into a beast. Much more noticeable difference than my convertible of the same year.
