Hi All,

I have been visiting this site for a while now, it assisted me in deciding to purchase a 1991 GQ 4.2L Diesel Patrol in March last year. It has been a great vehicle, taken me throughout the south west on numerous trips and up through the Kimberleys to the Fitzroy River and Cape Leveque.

In the last couple of weeks when about to take off it has been popping out of first gear.

Has anyone had this problem occur? It sounds like I may need to get the gearbox overhauled, although I am hoping it is something more simple that this.

If overhaul is required, does anyone now what sort of price I would be looking at and who in Perth would be the best place to take it to? What about Robson Brothers, or should I take it to a gearbox specialist?

Any feedback would be appreciated.

I would maybe check the mounts first. it could just be that the gearbox is pushing the lever against the tunnel an poping it out. i have seen it like that before. just a possibilty!!!!

Theres a spring that wears out in them, Bazzle was talking about it a while ago on the GQ list. It is not uncommon for them to go after few 100,000klms

I think a full rebuild it over doing it, but I would get it checked out first.

Check the engine mounts too. Ona trip recently a hilux broke an engine mount and among other things, this caused it to pop out of gear.

I have a similar problem on my 1990 GQ Diesel, except mine jumps out of 3rd under engine braking. I think it's only a spring, because if I lighly put my hand on the gearstick to stop it from moving, it doesn't have a problem. I haven't priced new springs, so I would be interested if anyone has any idea how much a set of new springs would be.
