I've never heard of an automatic transmission that shares the engine oil before; it's amazing that the same oil can lubricate the engine, the gearing, the differential and the clutchpacks while serving as the medium for the torque converter. It's also noteworthy that BMC enabled all 4 clutch combinations while most of the world's automatics were only allowing shifts, effectively, from 2 to 4 (though it might have been more descriptive to number the speeds from 0 to 3) in order to avoid having to flip 2 clutches at once. I'm sure this involved some compromises, but it's still quite an accomplishment. Thanks for posting this.
@@martinfidel7086 thanks, all good, car is running great, I've sent a few people in your direction, plenty of people needing parts for their automatics....
Interesting I owned a 1967 my 1 Mini Automatic from 1973-1976 and have never seen inside an automatic .I have seen inside a manual gearbox from a mini.Good video.
Thank you so much for this video, there arent many auto videos on TH-cam and with me currently doing my first ever engine rebuild on an automatic mini, your videos are a massive help, keep up the great work!
thanks, another channel has also just started a automatic build as well, classic mini workshop, so maybe this is also helpful, good luck with your rebuild👍
@@classicminiculture9800 thank you, I will take a look! What oil do you recommend for an automatic? There are too many mixed messages saying 20w50 Vs 10w40 JASO MA2... Very confusing!
Superb video. The lack of information on AP2 minis is shocking. I can find very little online regarding tuning, what power the AP2 can cope with, what modifications can be made to the box. I have been trying to find out what 3rd party ECU could be used as a replacement for MEMS to have more control over ignition and fueling. Really enjoyed the video. You're engine and gearbox look ace. The only sources I could find were the Facebook group and the Automatic mini Register and the book Foulis overhaul manual: AP automatic transmission for BLMC Mini, Austin/Morris 1100/1300, and Austin America And all the questions answered by Martin on forums! Cheers
Have you still got the old gearbox. Would you sell it. What was up with it. If not iv repaired a couple of them and happy to share knowledge with you or even show you.... the master rebuild kits are not expensive......
I've got a mini engine and automatic gearbox in my garage. Does the torque converter have any ATF in it or does it just use the same engine and gearbox oil? I want to put this engine and gearbox in a new shell as a present for my wife. I'm not a machanic and don't confess to being one. Just thought it would be nice . Anyone knows please as it the moment i can start the engine but when moving the triangle bit it doesn't take up drive . Thanks everyone.
Hi there! Quick question can you tell me the part number or where did you got the 2 seals of the drive? These appeared on min 3:35 of the video. Thanks
@@classicminiculture9800 Thanks for the info. I have an auto in my mini that I suspect is going to need some attention in the near future and a replacement is an option.
Hi, a few questions. The new gearbox I assume is from ap2 world? Which version did you decide on and why? What made you drop the engine below vs pull it out the top? And what was the approx time it took you to remove the engine? What is the model of scissor lift you use for the car lift?
Greetings, Yes gearbox is an AP2, late model with the park and larger crank bearings, the later gearboxes leak less because the park feature closes the oil port better, there is no right or wrong way to remove the engine, top or bottom works, personally, I prefer the bottom when doing automatics because you need a little more clearance on the subframe, the automatic gearbox is larger than the manual so it just gives you more wiggle room.
www.hbm-machines.com/nl/p/weber-professionele-3-ton-electrische-autopoetsbrug-poetsbrug-schaarbrug-230-volt, unfortunately the price has increased since I purchased mine a few years ago, I paid 1600 at the time.
@@classicminiculture9800 thanks, personally I have a 94 with park already and I wouldn't think about downgrading that. 🙃 So that gearbox is the middle one they offer. The upgraded but not the full racing gearbox? That's what I was looking at myself. I didn't think any way was wrong just curious why you decided that way and your explanation makes sense, I've not removed one yet but trying to come up with the best way to attach it the initial way. 😁 Thanks for the info and great videos!!
@@fantazmamurillo9819 sorry typo I use the 20w/50 SAE for the automatics, best oil I've used for classic automatics is Castrol Classic XL SAE , for the manuals us can use the lighter oil.

Very very useful and I'm sure this will help many with automatic minis. Doing a great job mate
thankyou sir........automatic shifter refresh and install coming soon
@@classicminiculture9800 message me if I can be of assistance :)

One of the best produced video’s I have seen, thanks
thankyou feedback is appreciated👍
Didn’t catch the torque figure for the central bolt for the torque converter is it the same as the flywheel figure?

thanks, we will try and bring more information on the AP2 soon, Martin is a solid source!!!
Good info.. you do seem to have a wealth of knowledge.. thanks for sharing
Great video, thanks for sharing
Thanks for the shout out much appreciated video looks and sounds great :)
Any time!
Good , where can i get parts for the auto transmission
AP2 world in the UK can supply parts for automatics.
Have you still got the old gearbox. Would you sell it. What was up with it. If not iv repaired a couple of them and happy to share knowledge with you or even show you.... the master rebuild kits are not expensive......
Isn't the engine mount at 11.12s upside down? At a glance it seems that way.....
good catch👍.....it was corrected before install

Hi there! Quick question can you tell me the part number or where did you got the 2 seals of the drive? These appeared on min 3:35 of the video. Thanks
What was up with the old gearbox.
Can the oil seal on gear selector rod be done without removing the rod ? Can it be done by taking cable bracket etc off
Yes it can, but you may need a tool to assist with fitting the new seal
PM me as I have these for sale
G'day! What oil do you use in your automatics (x W xx rating as well)?? Thanks
Another comment says he uses 20w50 Castrol Classic XL SAE
MA2 10W40 is the best oil to use especially on the later 1979 onwards units.
When you changed the shift rod from the old gearbox to the new one, did you use any kind of seal?
there is a small o-ring seal, AP2 in the UK have drawings on their website. ap2.world
Did you buy a reconditioned gearbox or did you rebuild it yourself? If bought would you mind saying where from?
Reg it was a reconditioned one from AP2 world in the UK
@@classicminiculture9800 Thanks for the info. I have an auto in my mini that I suspect is going to need some attention in the near future and a replacement is an option.
Can you show us how to remove a torque converter please
Do you know anyone that works on auto boxes. My 1994 1.3 auto is having problems

@@classicminiculture9800 thanks unfortunately not available in North America it appears. 🥺
Can you pls tell me what kind of oil it uses.my first oil change I used 10-40 mineral SAE . But Last gear started to spin .
I use 10/50, but if your last gear is spinning it sounds like its either a shift rod adjustment issue or the inner clutch is worn.
@@classicminiculture9800 Thank you . I will try the 10/50 . Synthetic or mineral ?
@@fantazmamurillo9819 sorry typo I use the 20w/50 SAE for the automatics, best oil I've used for classic automatics is Castrol Classic XL SAE , for the manuals us can use the lighter oil.
@@classicminiculture9800 thanks , do you have a video on how to adjust the transmission ?
i have issue MINI ROVER Mayfair 1.3L, reverse Gear is not working ,please suggest how to resolve, what could be the problem
Are you getting 4th Gear? If both reverse and top gear are not working its the Clutches in the reverse/top drum. Rebuild time.
Please please show the work you do on your dash.
coming soon......just waiting for the new wiring looms👍
