Gear change

Post by longhaul8 » Sat Apr 06, 2013 9:29 am

Seem to have developed a slight issue with the gear box if I set off steady all is well gears change as they should.

If I boot it the gears do not change up rev counter goes up to 3000 rpm and then it's like it hits a rev limiter.

Transmission oil level is ok.

Any ideas what to check before I go out and start to pull things apart ?

I'm not techie, but is the throttle position sensor (TPS) a possible suspect? Maybe check out old threads on that one?

I had a touch of that recently and put it down to too much veg oil for this miserable climate.

Haven't noticed it since topping up a couple of times with diesel only.

try the great pretenders (mel) tip, he said some recent troubles along these lines and were down to a fuel tank pick up filter partly blocked, on his recommendation i tried it, and was quite surprised at the results.
i had no real issues, just the odd flat spot for a second when coming off the throttle and back on, thought it maybe turbo waste gate problem or tps etc.
sorted mine out just blowing back to the tank.

cheers mel.
