well i have had enough of the auto.

 

i got the box rebuilt to a fast road box just over 18 months ago and while overtaking the other week it didnt change up and hit the limiter, so i backed off the throttle and it changed up.

 

i continued driving back home normaly within out over taking, but playing with it trying to find out the problem, in 4th gear it was running fine at a good operating oil temp. as soon as it changed down to 3rd i noticed the temp of the oil would rise by 20 deg within 10 seconds of the box changing.

 

The oil had been replaced 2000 miles before this problem occurred. The old oil was spotless.

 

i have a fair idea that the box is on its way to a failure.

i have decided to go for a manual conversion, however if anyone has any idea what could have gone wrong in the box i would like to know.

just really p1ssed off that after getting a rebulid to a fast road box it still dies on me, :cry:

by 4th you mean o/drive.

does it respond to you switching the o/d button on the lever off and on.

Does it go into lock up when in 4th also do you still get engine braking?

You can do a self diagnostic check on the gbox ecu, power light flashes response.

Usually if you are getting problem with autobox the power light flashes 16 times when you first swithch on.

I just had the manual conversion which i believe is a much better investment than repairing the auto. I know how you feel :cry: .

it may only be a speed sensor or something minor, but the autobox still has to come out and be repaired by a specialist. best of luck whatever you do. SWZ are doing a special on manual conversions for october

The gearbox still works as normal. Apart from the temp going up.

 

The temp rises when;

OD on and it changes down or when I manually go out of OD. It even rises when driven at low speed in 1st and 2nd.

 

As far as engine braking it operates correctly. The power light comes on once as usual when turning the ignition on.

I haven't run a diagnostics on it yet. but I will do that before I remove it.

 

Have just bought a manual conversion kit from AndyZ so I know what my job is next time im home. but got 6 months to do it.

 

Cheers guys

Mate have you checked the voltage of the TPS yet?

 

Mine threw a wobbly all the time and i found 2 of them had died.

 

Replaced and calibrated it properly and the autobox went back to being smooth and changing at the right points again
