Club 80-90 Forums

Hi all,

I’m a new T25 (1.9DG 4spd manual) owner and I’m working through the to do list on the van.

One of the issues I wanted to try to address was the sloppy gear shift and a whine from the gearbox in 2nd.

I’ve replaced the bushings front to back and dropped the gearbox oil and replaced it.

The problem is the whine now seems worse!

There looked to be around 3L of oil in the box and I refilled until the oil dripped from the fill hole (~3.5L)
I replaced the nasty looking oil with Westway 80W90 GL4 and added Molyslip GM6RA.

Can anyone advise on the error of my ways or is the gearbox just mullered

Thanks in advance.

what was the drainplug magnet build up like ?
whine only in 2nd, on power, off power ?
can you feel anything if you gently touch the gearstick ?

Hi Aidan.
Sorry for the late reply, I didn’t get any sort of notification on your response!
Noise is worse with power on and mainly in 2nd.
I replaced the engine over Christmas 2021 and noticed there was quite a bit of lateral movement in the input shaft.
I think I will be coming to you over winter 2022 for a rebuild.

oil  change it now to see what the drain plug magnet has to say; don't put it off for 12 months if it is bad, and make sure you have recovery sorted just in case for this year

Mine whined like a jet turbine under power so pulled the box and took it to a local gearbox specialist for diagnosis

Ring gear was badly worn hence the noise, the teeth weren't square edged but sharpened... if that makes sense

Only cure was to source another box and that has solved the issue

I changed the oil last year when I bought the van and the magnet looked pretty clean.

I will do it again though.

I have got RAC cover in place

Thanks for the advice.
