Inspection of a 904 torqueflite
I had it all put together and after all the advice from you guys. I decided I needed to be a little more patient with it.
I made some pump guide pins from cutting off bolt heads. Then tapered them and rounded them for better pump installation. I was able to line the pump up and get the gasket right without them but it was not a user friendly ordeal. Now the gasket and pump slide right on and are ready to be bolted in.
These pins help in a big way and to me are really a necessary tool to have.
Then when the pump was on.....I remember how hard it was to get out. I picked up a pump puller for that. Some tool that grabs below the splines and catches them while pressing on he input shaft. My pump has trans fluid on the seal so it should come right out with ease. They said this puller would work with a 727, 904, and all the GM transmissions.
I didn’t have any 8 point sockets......so I had to get a small set of those to torque down the band adjusters correctly.
I don’t know what’s up with that reverse band and why it had to come out so far except that I was using the output shaft and it went through the planetary. If I torque it to spec it should be good no matter what I think and then I’ll have a good frame of reference with how far we lift the apply. Pretty sure right now it’s wrong.
So now all of this will be a little more user friendly to do right. I got in a bit of a hurry with it. Then sat down and remembered all the study and work that went into doing his right....just to get in a hurry at the end and maybe miss something. It’s winter so it’s not like it’s going anywhere.
So I’m going to take it back down and measure the packs again. Get an air compressor and check them after compressing them.
Then torque the bands to spec the correct way and see what I come up with.
1/4 on the kick down and 1/2 on the reverse
I mean.....I need the right tools to get this right. I will also need them for the 700r4 I’m doing next.....which I might as well call it a 700....Sonnax...4 as it seems to need a lot of upgrades. Not that this is a mopar trans.....I have a lot of respect for the mopar transmission of the 904/727 family after looking at the Chevy stuff and how complicated it is and the level of Or lack quality gm put into it.
