MTX svc

[smccprez]

Hello, I want to svc the tranny on my 91. Has 175k.... What does it like?

Thank you

I've used both Dex3/Mercon and Mercon 5 in my MTX and I prefer the Merc 5. It seems to shift smoother and I have about 190k on my transmission.

Synchromesh gets a lot of play, as well as Valvoline.

I've tried a few, and ended up back where I started: Mobil 1 ATF

Seems like I have a few options..... Thanks for the input. I haven't been under the car except to change the oil so i never looked for a tranny drain plug but I'm assuming its fairly accessible? Also, how much fluid to use?

 

[Devin]

Yeah, unless someone took the time to install one, there is no drain plug. There is a fill plug on the left side (read: pointing towards the front bumper) that can be used to pump the fluid out (what I did), or you can do a search on the forum for instructions on adding your own drain plug.

Lol no drain plug? Im used to auto muscle cars & haven't serviced a manual tranny. I put pans w/ drain plugs on my autos..... Procedure please?

when you drive you'll hear clucking noise and the tires sometimes locking up. That means the pin popped out and you need a new diff. Seeing how hard these transmissions are to come by, may not easily find one again. I been through 3, till I finally smarted up and got the one in there now welded. I recently had to get the reverse fixed. These tranny's suck.
