Hi guys,

I'm new to this site and would appreciate any assistance.

I have a '93 9000 Aero with 144k miles and it occasionally pops out of 3rd and 4th gears. I have changed all engine/transmission mounts this week hoping to cure the issue, but it is still the same. 1st, 2nd and 5th are fine. In these gears the gear lever only moves slightly under accel/decel, but in 3rd/4th it jumps backwards and forwards with a 'clunking noise' even under very light load.

It is also getting difficult to engage 3rd and 4th gears at speed.

I am guessing its either the gear linkage, selector mechanism or synchro in the box. Has anyone seen the same issue- what was involved in fixing it and how much?

Thanks in advance
Simon

I hate to be the bearer of bad news but it sounds like the circlip on 3rd gear has gone. The same happened to me last year and it was a gearbox rebuild job. I'm not sure what the going rate for a gearbox rebuild is as mine was covered by Safeguard, but I'm sure someone will be along shortly with that kind of info.

I know how you feel as I'm looking at a possible ECM replacement at the moment.
