Hope someone can help . I have what i think is a problem with my auto box , how many times have you heard that ?. It seams to change from 1st to 2nd with quite a thump , sort of kick in the pants, I`ve adjusted the T P S and the throttle cable fitted an oil cooler and the oil is clean etc . all the other gears are fine . Any help would great Thanks

How have you adjusted the TPS?

 

The description of the change does point to a tps problem, of recent times I have seen several zeds with wiring faults on the tps so whatever you do to adjust it the signal the ecu see`s is corrupted, the only way to correct this is by rewiring the tps completely back to the ecu.

 

You really need to set the tps up on a ConZult system so you can observe what values the ecu is seeing not just what the tps is outputting.

 

Hope that helps

Thanks for that jeff , have you got a phone number for `conZult`i need to get this sorted. just one other point when i switch over to `hold `it changes up so smooth you can hardly tell its changed gear. does that still suggest T P S ?

Check the droping resistor under the wing, this is used to lower the line pressure for when the gears change. If its removed you get a superb 2-3 shift however 1-2 shifts are agressive.

Hi MTL, will have a go at that , where would i find info on it , ie which wing what values would i expect and what`s it look like . thanks `V`
