i think i have an oil spec problem in my gearboxi

its taking me like 10 minutes of driving in the morning before i can hit 2nd prior to that i have to skip to 3rd, and theres this whistling sound in 1 and 2
a friend told me that i would need thinner oil but the disadv here is i will lose full lubrication at high revs it would fly off the gears
so he suggested mixing oils what do u think
opinions greatly appreciated

Re: i think i have an oil spec problem in my gearboxi

Make sure you have the correct viscosity of oil.
This happened to me on our 145.
The mechanic put 80/90 in it, but it should have been 75/90 and it made all the difference.

Re: i think i have an oil spec problem in my gearboxi

If this is a new problem that is;
1) not related to a gearbox oil change
2)not weather related (eg first time car had been exposed to cold weather whilst you have owned it)
then you have a geabox related problem
If problem goes away itself when gearbox oil is warm then the viscosity of the oil may be at fault otherwise linkage adjustment/syncro/worn selector type problem.

By-the-way, do not mix different viscosity oils by yourself as no good will come of it
I am not sure what a V6 156 should have in gear box but should be some thing like a full synthetic 75W80 or 75W90 such as Castrol Syntrax 75W/90

If someone has put a non synthetic oil or a 80W90 when 75W90 is specified then you have gear change problems when oil is very cold-say on a 0-5 C morning
