C36 - gearbox / transmission failure on 3rd to 4th gear
I'm right now, moving to another state in Brazil and decided to go driving my C36 MG 1996 (my car is fully loaded with my stuff...)
So, the "fault" in changing gears began to appear after riding about 250 miles, not realizing the shift to fourth gear for a long time on the road ( 10 minutes) ..
After that, I decided to slow down drastically , because I thought it could be problem of overheating the transmission fluid as I was going on an average 80 to 90 miles per hour.
It simply started functioning normally ... shifting gears normally...
I stopped at the gas station to refuel and grab a coffee , and decided to check the level and color of the transmission oil since I had replaced with DEXRON III , plus the filter , and did not notice anything different or special (red fluid without mixing with water).
Can anyone help me or suggest what it might be?
Intend to follow journey tomorrow, but I fear that it may get worse or stop once along the way ...
best regards to everyone..
I hope the help of someone with more experience in this type of problem....

I would not drive any further like that.
I changed the transmission fluid last year, maybe in the middle of August...and I got a better fluid than the old one (DEXRON II)...I mean, DEXRON III...
My tranny is original...with no problems at all..since this episode...
But, I've checked today, by the morning (car still "cold")...and the fluid LEVEL IS HIGHLY ABOVE the maximum level mark...and I think this overflow fluid is causing thia failure...
is it possible to be this problem?
Maybe tomorow I'll drain all the fluid and get new one (DEXRON III) but i'll try to put less than it was before...
Do you think it's gonna solve it?
I take a ride today...like 20miles...and nothing appears to be wrong...all 4(four) gears had changed normally...
Awaiting for some tips or clues about it...

You must have one of the only C36's in Brazil, please post some pics.

I think over here in Brazil we have like 7 or maximum 10 samples of C36...
Mine, is a little bit different from the most of them, because it is US-SPECS, but Mercedes Benz sells just European versions over here...
Mine was imported independent...so...but she is a beauty...
So, let's hit the road to get there ASAP...

Took the c36 too the track on the weekend and boiled the break fluid.
The gearbox stopped going into drive staying in 3rd.When it cooled down it returned to normal. I also measured in the after market fluid.Now I have checked the level with a dip stick at 80deg. All ok ??

hope to see more C36 over here...
see U...
We are lucky that the C36 tranny are robust, and doesn't appear to be bad at all...
See U around.
I am looking at your C36 and I was wondering if there is any paperwork or a Mercedes name plate that says that your car is an original C36.
looks so different to mine inside.

Maybe there are some mods on it, like (LED's tail lights, OEM AMG rims (different from original )monoblocks, gearshift knob)
But, she is a beauty...and it's with 50K miles on it...
Which part did you notice that is different?
