Merctrans II
 

Hi, I'm wondering if someone can help. My MercTrans II does not engage back to neutral. Could it be a pump issue or a control valve issue? I'm a mercruiser 454 mark IV and TR drive. The engine will turn on when in neutral, but the transmission stays in gear. Thanks.

More info..
will it shift into reverse?

The MTii uses friction plates for FWD gear, and a band to engage the reverse planetaries. Best I can recall,, it requires pump pressure to ENGAGE the clutches..

Give as much info on the behavior. .
Can you reach the shifter lever on the transmission? If so, remove the cable and move it by hand - with engine off, does it move freely, do the detents feel distinct? With motor running, d escribe what happens when you move the lever by hand...

It shifts to reverse, but when shifted to neutral it stays in reverse. It will shift to forward and when shifted back to neutral it stays in forward. I removed the shift cable and cleaned the shift linkage. With the engine off the shift link feels very loose. With the engine running you can feel soft resistance. I think I need to rebuild it, but parts are hard to find. Do you know where I can buy a seal kit? The other issue is that I can't find anyone in RI who works with this transmission.

I believe it's a pretty basic transmission. (transmission 101) Anyone transmission shop should be able to rebuild it. You could probably do it yourself if you ordered the parts.

It can be very hard finding parts though, especially if the disc needs replacing.

I have some parts, gerotor pumps, complete seal kits, clutch’s and the rebuilding tools for Merc trans.

I believe the majority of the parts are Ford FMX transmission parts.

The friction parts are Ford FMX parts, but I wouldn't go so far as saying "most parts" are...

Cig28 says he has parts, so check w him.

The behavior of the trans doesn't necessarily suggest the need for a "rebuild". Sounds to me, it's more of a somwthing loose or worn in the shifting link inside. Something between the cable attachment arm and the actual spool valve that directs the fluid flow in the shift valve.

The shift portion of the trans does 2 things.
In neutral a valve blocks flow of hydraulic pressure to the clutch pack. In Forward OR Reverse, the valve directs pressure to the clutch pack.
The second thing the shift portion does is mechanically tighten down the reverse band.

Go ahead and drain the fluid (ATF Type F).
Remove the shift control portion (no need to pull the motor). I suspect a linkage problem or an O ring problem.

do you have a good Merctrans II 'shift motor assy' ??

do you have a good Merctrans II 'shift motor assy' ??

No I don’t sorry

Hi cig28. I have a merc trans II that ran out of fluid and needs a rebuild. Do you still have parts?

I Might have a gerotor/front pump with the input shaft , couple seal kits, complete tool set and clutch pack.

Awesome, I would take whatever you think it would need. I ran it out of fluid last year, re-filled it and used it last season with the inner seal leaking into the bilge. This year I pulled the moter fixed the seal and put it back in only to find that it is indeed bad. Let me know how much and how these transactions work and I will send you whatever you need.

i just had a velvet drive for my ex sea ray rebuilt,,,guy said that was all ford clutches,,,been that way for years rebuilt it for 500 bucks?? he is in algonac mi

PM me your phone #.

The borg Warner velvet drive is a totally different animal to the mercury transmission.

oh...sorry on that,,

not ford fmx trans parts inside, but ford C-6 transmission planetary & associated parts. completely different ford transmission. just sent it to bam marine in pompano beach florida.

Flash I stand corrected. I didn’t realize borg Warner trans used Ford c6 components. The mercury used some Ford FMX components.

I know this is an old thread but I’m looking for 2 seal kits for the merctrans II. Do you have any available or know where I could obtain them?

Sorry I’m all out . You can try Mel riggs in wisconson.

Will do thanks.

thank you very much, Riggs Marine was able to hook me up.

Merc Tans MCM-E
 

Hi Cig 28. I have Cig 24 with Merc Trans MCM -E in need of an output shaft; forward piston housing and gasket kits? I have talked to the "Legendary Mel" @ Riggs Marine but no luck. Do you have any connections?

Sorry but I don’t have any kits and wouldn’t know where to start looking for them.

MercTrans II MCM-E
 

How about a complete MercTrans II MCM-E ? Am interested in purchasing the complete unit.

I have 3 transmissions but the just parts transmissions. Nothing is complete and they would need to be rebuilt. if someone was interested in then they would have to be local pickup I’m not shipping them. $100 each.
