You wont want to hear this, but I had something similar to what you describe (well, ish). T/M malfunction and only about to select 2nd, 4th and 6th. It was a snapped shift fork, so box out, replacement fork, thing it fits on to and a new clutch as well (might as well since the gearbox was out of the car). The car at the time would have been about 5 years ago with 20k miles on it and I just tool around in it.
Wow thanks for all the replies all and for the link to the helpful guide. Please forgive me if I don't reply to each one but know I really appreciate it!!!]
From the looks of the guide posted and ones I have found online, it certainly doesn't look like the GR6 is too painful to work on.
I happened to find Jacks Transmisions online yesterday and found a video on youtube which explains the solenoid behaviours. I'm very appreciateive of their video and have emailed them to say thanks. I've posted a picture of the solenoid behaviours as I understand it from their video.
(hope that's readable! I've attached a copy too just in case).
I'm not ruling out the failed clutch or fork issue but I suspect from the error code, the first place to start is the solenoid(s), so this is what I'm thinking:
1. Drain oil, remove the sump
2. Remove the solenoid/ACM block
3. Replace the failed/jammed solenoid (might just do them all, I know they are expensive but don't want this issue again!)
4. Refit, replace both filters, refll with new oil
5. Reset error code and test
I know there's a couple of comments suggesting I should leave alone and take to a specialist andI thank you for the honest views. I've not told you about my history. I've got a mechanical expertise and am not afraid of transmission/engine rebuild work having done both on Supras, Skylines (32 to 34 (...and now 35 LOL), 300ZXs, Imprezzas, Evos, GT4s, 200SXs, Silvia's, etc... I just appreciate knowing where to start
However, I'm not macho about it, I will raise my hand to ask for help when I'm not sure about something. So with that said, I'll also contact AC and Jacks to see if they can offer any guidance. I'll need to buy parts and maybe even upgrades if any are within easy reach so the most helpful will get my custom
Thanks to everyone for their support, input and help. I'll keep updating as I go along.
Fair play to having a go yourself.
Take lots of pictures as you strip it for reference.
I don't know of a U.K. stockist for the filter but power enhancer flog oil at the right Money, try and use Audi 20 as a discount code.
Thanks for this, good intro into how to get access the ACM. I've got that bit down, just need to know which of those solenoids has failed, I suspect it's the tall ones at each end, they control fluid flow to the 'smaller' solenoids
