I just got home from Eriksson Industries in Old Saybrook. My transmission was dyno'd and worked! I would never have taken on this project without Gary, and I will find a way to thank him. I did buy the product he recommended, and am absolutely thrilled that my first automatic transmission repair was successful! Thank you Gary for teaching the world how to fix these common failures, pushing otherwise awesome cars to the scrap yard.

Awesome!!! Great job, Glad its getting back on the road

Gary: Good to talk to you today. I think you for your advice and guidance over the past week. I'd like to point out to anyone watching your videos that they are an excellent source of education on both the practical disassembly and assembly of these transmissions and the theory of how they operate - explained in laymen's terms. From my own experience I'd like to add a further caveat to the A and B drum weaknesses: When I tore down my transmission, rebuilt just 4K miles ago, I cleaned the sump of what I thought was clutch dust. It turned out to be the remains of the B drum seal which had dissolved completely, causing the car to stop moving. Everything else inside the box was brand new. Caveat Emptor. Cheers, Peter

Gary, Thanks for all the videos! I have a 2000 Jag XK8. I replaced the broken A drum and inspected the valve body. Valve body looked good, fluid was dark and not a lot of material in pan so I just replaced the A drum. I still have the same very delayed enagagement about 2500 rpm and slams into gear. Reverse works fine and the trans is in limp mode. It sets fault P1722 Stall Speed failure. After rechecking the repair the A drum is intact and all seals look good. It doesn't seem like a control issue it seems mechanical, . I have not torn the trans down completely. I wanted to ask what else to look for and could I have a torque converter issue?

Great advise on the proper alignment to get the oring seal to sit properly and not tear! I've fallen victim (self inflicted)!!!

hello gary, first thank you for your great devotion to share these infos with us, id like to ask you about my 5hp24 (bmw:A5S440Z) wich it stays in 4th or 5th gear, i think, it seems to be high gear because the car can t advance in even a small hill, and all that without a FAILSAFE TRANS PROG in the instrument cluster, however the reverse is good. and also, what happen if i try to disconnect the ECU?. respects sir RÉPONDRE

Thanks Gary. The comment section is a fantastic source of information! I will be taking notes from them over the next days. What is that sanding block that you use to sand the valve body after the gasket was removed? Thanks again! Best steve

Hey, Gary. Great video. I’m having a 2-3 and sometimes just a 2 slip on my 740il causing it to go into failsafe prog for incorrect gear 2 ratio. From what I’m gathering in the comments, I should be suspecting a different drum than my A-clutch? I’m about to undertake the overhaul and want to make sure I have everything I need. Also, I’m having a lock up in 5th that’s weak and goes in and out at 70mph. I was advised it’s the torque converter lock up clutch. Any advice? Thanks in advance.
