tommyfn Member Date registered: Jun 2014 Location: Norway Vehicle(s): 300GD lwb 87' Posts: 28 | GL275 transmission trouble Hey. Im having trouble in my 87' 300gd, the transmission is popping out of 1st gear occasionally... I changes all the rubber rings on the rods under the car, it made it a little better. They are not bent, and for me it looks like they are positioned right. I loosened all of them, when the box was in "N", and they were all in line. I have ordered oil with 236.2 spec, and will change when it arrives in the mail. But im afraid its worn out? What can be wrong here? Regards Tommy | ||

That is the basic position when adjusting your shifter rods. gr. Bram | ||

It was also adjusted correct. But i tried to adjust it so it pulled a little extra in 1st, no improvement. Kinda grey oil in it, i changed today. Worn out ??? Its so strange, cause when it is engaged in 1st it works well with absolutely no weird sounds :/ | ||

I find it easier to get it into 1st if i roll slowly (5km/h f.example) Indeed, maybe syncroniser rings or the clutch doesn't completely disengage. When it comes to rebuilding, I would go for a different transmission instead of putting a lot of money in a GL275 (717.42x) gr. Bram | ||

tommyfn Member Date registered: Jun 2014 Location: Norway Vehicle(s): 300GD lwb 87' Posts: 28 | Re: GL275 transmission trouble I will try to change brake fluid on the clutch. And maybe it works a little better while I find a suitable 720.1 case from a 280ge. Im not satisfied with the getrag so wont cost any money on it | ||

Always check if the starter is on the correct side (right side for m110). | ||

tommyfn Member Date registered: Jun 2014 Location: Norway Vehicle(s): 300GD lwb 87' Posts: 28 | Re: GL275 transmission trouble Yeah, I've considered the 711.116 case since I plan on getting bigger wheels anyway and the 5th gear with 0.8~ ratio would not be needed. But I prefer automatic so hope i can find one and get all the vacuum details as well! | ||

tommyfn Member Date registered: Jun 2014 Location: Norway Vehicle(s): 300GD lwb 87' Posts: 28 | Re: GL275 transmission trouble Changed fluid on the clutch today... And i dont know for sure but I think it got a little better.. Maybe some of the problem was that it didnt disengage 100% ? And the grey oil was because of all the synchroing and grinding gears? :p | ||
