2 litre gearbox um100 problem

Post by ginger colin » Mon Sep 15, 2014 6:24 pm

Hi

It looks like my box may have finally died.

A filter clean and new oil did help but it stared hesitating going in to second again, then the dreaded hold light flashes.

It's fine cold but when hot it's getting worse.
I thought Ava had solenoids but they are not listed for the 2 litre.
Has anyone rebuilt / re sealed the solenoids.
Can anyone source a um100 box. I'm struggling like mad

Alternatively recommend a box specialist in Essex.

Have you checked the level is correct when the gearbox is hot? I found it really tricky to get it right.
