Gearbox problem anyone guess what it is?

    I recently put done a conversion on my car from a 1.6 Mivec to a 1.8 GSR turbo.

    Before this there was no problem with gear selection or getting jammed/not going in.

    I really cannot understand the problem.

    It would be driving along grand, then you would drop out of 2nd come to a set of lights stop. Select to go back into 1st and it take a good force for it too go back in.

    I just don't get it, and its only after the car heats up...

    Any idea's anyone?

    Gearbox ****ed?

    New clutch?

    Simple fix ?

    Anything ?

    I'd say when you dropped the new engine in, the standard running gear in the 1.6 couldnt handle the extra power being put through it.

    Did you upgrade the brakes/clutch/tyres etc when you dropped in the new engine? By rights you should have done the above, along with the gearbox from the 1.8 Turbo.

    Are they a hydraulic clutch or a cable?

    Sounds suspiciously like a problem I had when I fitted a new clutch cable to my kit car. Routed the cable the wrong way and it was too close to the exhaust. Heat from the exhaust melted the plastic on the cable, to the cable. Very hard to find any gear when the car was warm - no problem when it was cold.

    Yeah I uprated the breaks on the front too drilled and grooved. I seen a few of them done before with the 1.6 Mivec gearbox with no problem, I have a Mivec clutch in the car.

    Its cable, I am going to have a look at it now, and get back to you on that one, its sounds the problem is something extremly silly..

    Not related but an old mechanic friend of mine says "mitsubishi gearboxes are soft... not suitable for women" :)

    Would a low/zero level of gearbox oil be behind this problem?

    Me owl lad told me just there 10 months later that he noticed the gearbox leaking oil during the conversion.

    Well it certainly wouldn't be helping

    Low oil will definitely cause the problem.

    An oil change will almost certainly help, it might even cure it.

    when you stop the car and gears are fine you would be looking at an internal problem!

    Thinking back there paddy, I was stopped one time, when the problem happen, and I could not select a gear, while the engine was running hot... IIRC, when stopped turn off and hot it would select either..
