Hello,

I need help finding out a little bit more about a JDM transmission I bought to put in to a 92 eagle talon tsi. I did a number of searches here at DSM tuners and google and couldn't find any info on this transmission code# RDOT(see attached for image). Has anyone seen this transmission code# before?

The Mitsubishi number is MD720131 meaning it's a galant vr4 transmission from what I've gathered on the forums. I just want to know more about this transmission code # and if there is any difference in gear ratios between the galant vr4 transmissions.

Thanks!
Dan

Old thread... but I just bought a transmission with the same stamp. Its got steel shift forks. It had a 23 spline output, dude took the first cover off so I could check it out. I was hoping it will work as parts for my current evo 1 box.

That r"diamond"dot stamp is on Mitsubishi replacement transmissions. The 3000gts use the same stamp.

Sweet thanks. Im gonna have to crack it open and see whats inside now. Its either an early evo 1 trans with the 2.57 1st gear or it could be a standard 1gawd trans with evo 3 shift forks. Either way it has cast steel shift forks so its a cool find.

The 92.5+ dsm transmissions have a steel fork for 5th. If all that was removed was the end case you probably didn't see the 1-2, and 3-4 forks.

Donnie you are correct. My 91 trans had aluminum 5th/rev. I cracked the trans open today to check for serviceable parts and the 1-2 and 3-4 forks were aluminum. Thankfully the front diff ratio was 3.545.
