Awesome. Thanks. Just about to hit the bunk but I’ll read that tmrw. Where do you guys get the workshop manual from? I’m currently downloading one (10gb) that I just purchased. Hopefully as detailed as the info you guys kindly provide!It might be that range change just needs adjustment.
Here is the procedure:
Cheers, I will send you a DM about it - Maybe Dropbox? Currently looking at AUTEL and other systems and compatibility! I’m sure I was going to bed 90 min ago…!Re manual, I used to use a CD or DVD disk, but now it’s downloaded onto a Microsoft Sync and also on a little “dongle” with a USB male plug sticking out. I wonder if I can email the thing to you? I will look later as to its “size”.
Also looking at changing the fluid as the stuff I ordered has arrived. I hope it’s an easier task than the linkage!I would definitely test that transmission fluid.
SAE 75 W-80 (235.41)
I'm thinking...might be a solenoid for range change...
When you shift from 4th to 5th does it go to neutral or does it stay in 4th?
Hmmmm… Seems I only get 2 digit codes, e.g. 24 if the park brake isnt on when I do the teach and the others are 21 or 17 usually. I bit the bullet and got the Unimog guy in from the city (1 1/2 hours away) and he ran the diagnostics on it and it came up fine. He then started swinging spanners on the forward end of the transmission. he had to leave before finishing but when I last saw him he said he was going to do some more research and some back soon to continue, as well as change the trans oil. - Fingers crossed.The GS (actually all) error codes should be 2 capital letters, like GS, referring to which computer system. Then 5 digits, not 2!!
The “n” in parentheses refers to the computer controlled fixed rpm fast idle switch, which for normal driving should be OFF. I use it rarely for stuff like running my hydraulic generator at 890 rpm for example. When ON the truck is likely undrivable, at least in a normal way. The switch is on the panel between the seats.
Thanks. Yes I had seen the list but couldn’t source the approved ones. Looks like the MB guy can!EPS controller = GS computer? Too bad, I have a spare in a box in my camper’s pantry, cost me ~$200 when Unimog North America had it’s “going out of business” sale. Wouldn’t work in yours. What transmission fluid were you going use?
Do you know about this list?
Go first to page 231.3The Mercedes-Benz Specifications for Operating Fluids provide you with an overview of the requirements for the operating fluids and for the recommended products. Operating Fluids are products necessary for Mercedes-vehicles / major assemblies, e.g. fuel, engine oil, gear oil, ATF, brake fluid...bevo.mercedes-benz.com
Yeh that’s what he took, I guess there is a microprocessor or something integrated in it? Anyhow I’m at their mercy, no way he will install something I get. Japan is funny like that and in this instance in particular, I’m over the barrel.
