B&M Quickshift Problems

[Big Bob]

Hi Guys

I have had a b&m shifter fitted to my car for a few years now and it has been a bit of a b**ch when the car has been used for a while becomes really stiff and difficult to use but today i lost my rag and have had enough does anyone know why it keeps going stiff when it gets warm.

 

[B5 BDJ]

so when the car warms up, the shifter goes stiff?
changed the gearbox oil recently/ever?

 

[Big Bob]

yes new oil only 50 miles ago due to drive shaft problems

 

[B5 BDJ]

do you know which exact oil was used (fully synth/semi synth and grade?)

 

[Big Bob]

75w80 castrol

its not the oil
it did it before the oil change and it does it after the oil change and has been getting gradually worse over the years

common problem with these mate. its do do with the metal expanding or something IIRC.

They all do it.

Not sure if there is a fix to it mate you might just have to cope. Someone might be able to give you a proper diagnosis but no, its nowt to do with the oil lol

Just shitty design and the bushings tighten up.

I hate them.

have you got one of those franx? i'm after one but if b&m are dodgy this could be what i'd get.

 

[franx]

not yet, it's on the wanted list !

These came out very good in an indepedent test, i read about it on a French site.
Sorry ca'nt remember which/where....

The design is better, for less $ .. best bang for the buck

I dont think they are a good idea fullstop TBH as the gearboxes don't exactly like to be rushed at the best of times.

a year on after this was first posted, has anyone else had any problems.

Put that crappy oil in my car and I had problems to get the gears in (some of my mates here hade same problem) especially when cold. Changed to the oil you are supposed to use according to Renault (Elf NFJ 75W80) and the gearbox is smooth as butter.

Change the oil!

[DannoTheGreat]

is b&m shifter and bm shifter the same?

is b&m shifter and bm shifter the same?

you mean the mb shifter that franx has linked to? its nothing like the b&m! Ive had mine mb shifter for 2 years now without a problem, its great.

 

[Jamesstone]

have driven two cars with the B&M, did not like it at all

 

[Duke172]

Ive got a b&m short shift on my cup, after long run becomes really stiff too. Fact is I actually like it when its like that lol. Goes back to normal when it cools down.

 

[Nick r26r]

mine is also really stiff , i like the look of it in the car though , not sure whether to take it out or put the standard unit back in ???

 

[franx]

In my case, it was way to heavy to shift when first mounted. I soon found out what the prob was.
I called Maurice down at MB and he said i probably tightened the nut that connects it to the rest of the linkage too tight (so bottom of the actual stick, connecting it to the selector rod ? ) Loosened it up , job done , happy smooth shifting going on for a while now.

This must be the prob for most issues i've read on here; gearboxoil suddenly being the case can't be possible

The Castrol is very bad in JC5 Boxes I have tried myself, could not get gears in propperly.

 

[2 live]

castrol oil is bad full stop.

 

[Andyman]

What would you recommend ?

 

[GodSpeed]

Elf Tranself NFJ 75W 80

Thats what Renault specify and it works fantastic compared to the Castrol Ive tryed. At least here in Sweden the Elf oil was a bit cheaper as well was a bit hard to get hold of though.
