904 Transmission Stopped Going Into Gear

Duster captain, would you like to borrow some pressure gauges? I will send the ones I used in my photographs if you would like to try them. Let me know.

I am having a frustrating problem with my trans.

The car is a 1972 Duster with a 225 slant 6 and 904 3 speed auto trans. This is my first MOPAR project. You can follow along my progress so far on this thread: 72 Duster Resurrection

Its the author himself! I'm going to get my own set of gauges but I appreciate the offer. I will probably bother you with a few questions when I get under way.


I would recommend using a good local supplier if you have one in your area, such as Transtar Industries. Many of the kits work just fine, but if there is a clearance issue during reassembly, a good supplier can work with you to get the parts you need. Another good way to go is using a specialty shop, such as A&A trans, Cope racing, or TSR racing. The parts are all the same no matter who you get them from, unless you buy a specialty part one of them makes on there own.

Good tip, I'll hunt around in my area and see what I can find. I see that most places have different "levels" of rebuild kit. Is there any way to know what I need before I open the trans up? Should I just get the "basic" kit for now?

Think about this.
There are more parts in a plastic model car kit.:D
That's good to know!
