thank you! will have a look and see how much of a faff it is to remove it, might be able to look today if the weather keeps up

Very kind of you! I know when I had an LS400 I indeed had to change the ECU because of something similar. I just would have thought a failing ECU would cause more hassle than slipping gears Okay so pull the ECU out. Am I gonna set off an immobilizer if I remove it?

Seems to always be aimed at the 6 speed just like that video. I can't even be sure it is ECU related which isn't super frustrating as I can't just keep chucking money at it. Surely if it was ECU it would do this regardless of temp. I think I'm still leaning towards fluid again🥹

Well short lived as ever. Overall it is better than before. But when cold it is still a bit hit and miss with a little slip through lower gears and dropped into neutral once whilst on my way out the estate. Again once warmed up it was fine 🤷‍♂️ Does anyone have a simple checklist I can run through with a garage or tech? Gearbox itself? Fluid again? Sensors? ECU? pulling my hair out 😞

I will do, I had such high hopes and plans for this boat it would be a shame to bin it off. 🤞 Everything remains the same and I'll do a premature trans fluid service this time next year to keep it stable. Still on the cards Wheels Exhaust needs sorting. It's a bit brash for my liking The rest of the sound system And of course timing belt!

I drove it home today for the first time in a month! I feel like it slipped once on the way back but no dropping out of gear etc. like it was before. Could it be all that new fluid working it's way around finally. The mysterious genuine £19 MAF sensor from Amazon? Pure luck? Who knows. Will keep the thread updated if it comes back as I'm sure I won't be the last poor bugger to experience transmission issues. 🤞

Thank you! Well will be trying the new MAF today and then I suppose I'll be pulling the ECU out lol

Nope 😞

I think the second image is the later one, I didn't test it so is more pressure a leak or less? Haha am gonna try a new MAF sensor as stupid as it sounds. And double check wiring etc.

Thank you but probably still means it could not be that. Its not like running out of fuel where you know what the issue actually is.

and also means immobiliser and keys etc? or is the engine ecu different?

is there going to be an obvious way i could check that though? don;t really want to lose my car for even more time and more money if it isn't that 😞

Doesn't appear to be any leaks between the 2. From 9am to 1pm.

Thank you! Will update once I know more 🙂

Long story not so short. Toyota Celsior 2002 5 speed I got the car new years eve. It slipped between 2nd and 3rd gear. I could live with it but best not to, Sometimes it didn't like to engage reverse, like it goes into reverse but doesn't move instantly. Asked my local garage to check / top up ATF if needed Did this no change if anything the reverse bit got worse. Shortcut thought just change the box over, Done that and was great for 1 whole day. Now it drops in and out of 1st gear whilst sitting in traffic. Into neutral it feels like. Then reverse is hit and miss. Confusingly seems to be better / fixed when warmed up fully. Car is off the road. Just had 9 new LTRs of fluid and strainer fitted and filled etc. Other than this new but used box being faulty could it be something else? I thought the garage may have messed up the fluid etc. But now seen the invoices it was T-IV like it should be. Any suggestions? Otherwise I'll end up stripping the poor thing 😔
