Turbo Dodge A525/A520/A555
Transmission Rebuild Parts List

Difficulty-Factor-Small-2Note: Though the part numbers and potential suppliers are provided herein, it should be noted that a factory service manual and some specialized transmission rebuilding expertise will be required to rebuild a turbo dodge transmission.  There is also a fairly large set of Miller specialty tools required to disassemble/reassemble the transmission internals and you will also need a dial indicator as well as a verinier caliper. Without all of these tools and a full compliment of other more common shop tools as well as a press with a variety of accessories, rebuilding a transmission on your home shop bench will not be possible.
