well CHRIS i dont know what is expensive, £40-00 plus a drink for my mate plus p&p, ive seen these ECU`s go for all sorts of prices on ebay but i consider myself lucky to find one at all, as ive emailed untold breakers yards, plus people on ebay & been to as many breakers as i can find thats why i asked my mate in hemel to scout his local yards [used to be mine too as i was brought up there], but like i say the waiting aint doing me much good but if it cures it you will know about it, oh by the way i know you were jesting but sarcasm is the lowest form of wit
, luckily im the lowest form to understand it
,,,cheers mate!
So it is back to basics then.??
Had exactly the same problem crop up last Sunday evening. 95 elite estate.
with the box sounding like a bag of bolts, managed to get back home in 2nd,
managed to get to it last Wednesday for half an hour between the downpours. After having looked at the book of lies and deciding not to go there, was going to post a question here but did not get round to it.
Having just read these posts glad I did not. that could well have meant 2 of us looking for a transplant.
So anyway if you take what TB said about the gearbox ECU you had better believe it, so that's one problem sorted, the box has been changed how many times ?. if you aint convinced yet then you may be better off getting rid of it. You have belled out all the wiring and components. You have checked out the middle (Blue) engine main wiring harness, getting closer.
Start at the begining.
This is what I did as my first line of attack. slacken battery terminals, turn ignition off remove battery terminals. Remove the battery. Now check the first plug and disconnect it, check there is no condensation there and reconnect making sure it is locked in, reconnect the battery. switch on ignition, you should have arrived.
That is what I did which solved the problem dint go any further. The moral being recheck after every component you check, you are fault finding.
from the sounds of my box the brake bands and solenoids must have been having a merry jig. Both ECU's talk to each other many sensors also talk to the gearbox. it's a nightmare especially with such lousy wiring diagrams to try and work with.
hope this helps you, because at the moment you are and have been way off track.
