1G E33A Galant tranny on 1G N/T FWD DSM

[Yamadaaaa009]

I have a 1990 Mitsubishi Eclipse GS.
My transmission has been making grinding noises every shift. It becomes louder at higher RPM and when downshifting. My mechanic recommended me to just replace the whole transmission as they're not sure if rebuilding would fix it totally. DSMs are rare in my country so finding a transmission from another Eclipse is nearly impossible but the E33A Galant (FWD, n/a) is very common here.

Would their transmission fit? I've read somewhere that they're also an F5M22 tranny but with different gear ratios, would it affect anything or is it just a bolt on?

Definitely verify the whole transmission code on any transmission you buy. It looks like a F5M22 from a Galant should bolt up. Same starter plates, same ring gears.

Use the transmission mount from your Eclipse. You’ll also want to use the shifter cable bracket that bolts to the transmission from your Eclipse as this is not a part between the two vehicle models. Past that, depending on the year of the transmission you get, you may have some issues with shifter cables. The gear selector shaft on the transmission is, like the 1990 DSM, different from later model years. So it would be very helpful for us to help you if you could provide the whole F5M22… codes from your transmission and any potential units you are looking at. From there, we should be able to decipher whether you will need shift cables also or not.

The gear ratios only matter for overall drivability, not for whether it physically works or not.

Been a while and I haven't gotten across a transmission for my car yet. I've been asking around and unfortunately they couldn't tell me the exact model of the transmissions of their Galant (they couldn't find the model numbers or claim that there's no markers). Is the shifter cable my only concern? If I'm able to get a transmission with the shifter cable and the whole shifter assembly, would that give me less of a headache to install?

It would be on this pad, in the red circle.

Thanks for the photo, Marty! @1990TSIAWDTALON

As possibilities for direct swap, I’m seeing F5M22-2-XQZH, F5M22-2-XPZH, or F5M22-1-RPKH. They should be directly compatible with your shift cables as well. If it is not one of those, you may need to source the cables for a later model year transmission. The Galant cables may work but I have no way of knowing for sure.

Sorry for reviving a somewhat old thread but figured I didnt need to make a new one as it's related. Found a F5M22 XPZK trans which I believe was from a 91 Galant E33. Will this be bolt on to the 90 Eclipse?

It looks like that transmission (-XPZK, MD995578) has the 1991+ shift selector arm (MD735587, in ASA as M/T Gearshift Shaft Kit, the one that is installed through the case into the transmission). So, basically a 1991-1994 non-turbo transmission.

To make it work, I’d refer you to 91-94 Transmission.

ASA also shows the cable bracket, the shift lever arm that bolts to the transmission, and a different pressure plate used for this transmission versus a 1991-1994 DSM. Same clutch disc, throw out bearing, clutch release fork, axle seals, and flywheel, though.

Based on my other thread I currently have the KM206 trans instead of the F5M22 that came with the 90 DSMs. Based on ASA I should have the same part numbers needed for the swap MD730758, MD719962 and MD723865 which means I should be good to do this swap (I hope ). Thank you for the information! Especially with the trans thread, I've been looking for that 91-94 Transmission thread for ages but I can't seem to search for it.
