THIS one I started in the right forum (unlike my Rebuild Diary). There is starting to be more discussion about transmission issues around here, and I think numerous posts and threads and input from so many good sources has spurred that. Brian (I think his nom de plume here - Brain is a misspelling - but it fits, he is incredible with what he is doing) has provided even more fuel for the fire.... I want folks to know a trannie CAN BE a DIY project.... it is not rocket science.
Anyway I am not trying to pretend I know a lot about using a pressure gauge. In fact I didn't even own one until about a year ago. Yet... I think they are not often used, even by transmission shops. Why? Well at shops it really doesn't matter what part inside is not working right... they will pull it and rebuild it..."$2000 please.... thank you ma'am.... I haven't a clue what it was but I fixed it..." (and if you rebuild it all you will). And in fairness if you pull a high mileage trannie, you should rebuild it! Yet... I wanna have some ideas what is good and what isn't..... and on electronic trannies.... nice to know if the guts are ok and the "brain" is not working right (was true big time on some 2000 model year trannies!). SO, the modest pressure gauge.
A transmission pressure gauge is just a 300 lb gauge on a long hose....
This one is made by KD tools. I picked it up off E-bay for $40, never used.... and as luck would have it the threaded end, without adapters, fits the A4LD case pressure port perfectly...
(pic coming)
I plan to hook this up to my A4 with 209K on it and record and share pressures, then do the same with the rebuilt I'll be putting in... with a NEW pump etc.......
but, until then, we can discuss what the "ideal pressures" are, and discuss what variations might mean.... as ever, everyone should feel free to join in.
