MG MGF Technical - GEARBOX BLOCKING
|Changin gears ( even from neutral to first) is becomming very difficult. I need to really pull or push the stick to change gear.|
I was adviced to check the oil level of the gearbox and indeed: i had about 50% of the gearbox oil left .
Somehow the gearbox oil level dropped dramatically , is this normal after +- 55000 miles?
Anyway, a mechanic filled the gearbox oil reservoir to the maximum ( added 1,2 litters of oil) BUT the gearbox is still "sticky" in a way that you need to pull it like crazy to change gear.
|Common in any way, that the gearbox oil needs to be checked. My old MGF had a loss as well after 50k km.|
Though if you need a new gearbox, then I can sell my second hand gearbox (1.8i only).
IMO there is usually no loss of gearbox oil (if there isn´t a regulare leak/seal problem of course !) . The main problem is that on all MGF´s I have had the chance to look at / speak to the owners the original factory fill-up has been very sparse !! As said in an earlier thread some years ago on this BBS - check the gearbox oil and after at least 2 years of driving change to synthetic oil. Gearchanges will be noticably better ! The oil should be a GL4 type BUT some synthetic brands do label GL4 / GL5 and this is also fine. Stay clear of ordinary non-synthetic oil labeld "GL 5" as this oil is intended for hypoid cut gears and contains a bit too much additives that can affect the syncromesh gear rings and worsen the gearchange even more ! I am now on my 5´th year with syntetic gearbox oil and the gearchanges are very slick - despite a very short gearstick..

|Could there be an other reason for the blocking gearbox? ( damage to mecanical parts or gearbox settings-tuning? )|
You would expect that an oil refill solves the problem but it didn t.
are You sure it is the gearbox? Might as well be a clutch -related problem. Hard gearchanges ( with normal working gearchange linkage) is often due to the clutch not diss-engaging fully. This makes the life hard for the syncromesh and gives a stiffness to the gearchange. The problem could even be related to the clutch cylinder and release cylinder at the gearbox end. Air in the system ?

|How does one check and change the gearbox oil?|
Perhaps the cable gets stuck somewhere (could be the "tube" where it slides in ?)
