I really enjoy watching a real expert doing his work with transmissions. Really helps me out as a DYI mechanic🤩 you definitely deserve my sub as well as my respect🤝

Thank you, glad you enjoy and thanks for subscribing

Great troubleshooting Gary! Most shops would've just thrown a banner kit and solenoids at this and never bothered to actually find the real problem. Hope this fixed the unit. Keep up the great work. Would love to see more units that come through your shop.

[@GaryFerraro]

Yes, Customer called me and said car is running great, He lives in Buffalo and says any trans work will come to you. I hate just throwing parts at the transmission because if it doesn't fix the problem I feel bad charging them, I also hate working without direction

[@madhavagrawal8356]

Great work as always Gary, the precision as always is topnotch . Keep up the good work!!

[@GaryFerraro]

Thank you

[@billk5727]

Great problem solving! I like your Test Not Guess approach, and I'm sure the customers do also. I'm finally getting ready to pull out my 4t65e. Hope you can help out with upgrades for it. It's been brutally hot weather so TakeCare, Bill

[@GaryFerraro]

Sure, No Problem, Your in New York?

[@billk5727]

No, I'm in Maryland. Same east coast heat wave though. I bought the Corvette servo piston kit from Phil, he's a great guy to work with!

[@GaryFerraro]

So your building a 4L60E?

[@billk5727]

@@GaryFerraro No I just did some general maintenance on the 4L60E and that one upgrade. But the 4T65E will be a complete overhaul with all upgrades.

[@GaryFerraro]

Bill K ok. Let me know when the trans is on the way out

[@martineztransport]

Thank you I'm very impressed with your work

[@GaryFerraro]

Thank you and thanks for watching

[@akvabullet]

Would be more benefit for us if you give more info about parts where to find them and how much cost,anyway thank you for your time and effort to help us on DYU.Thanks again.

[@GaryFerraro]

Ok, will do. If you need parts, depending on what it is, I can let you know where to go

Hello Gary, Thank You for your very details videos. I have a problem with my BMW e65 transmission, you may encounter: While driving, the gearbox error 4E89 - solenoid valve 1 or solenoid valve 2, mechanical lock suddenly appeared. After turning off and restarting the car, the error disappeared and I reached the place (10 km), but when stopping the car, the gearbox automatically switched to P mode. When I tried to change to R or D, it automatically changed to P again. mechatronics and the following parts were replaced: a set of solenoid valves, a separation plate, pistons, seals between the mechatronics and the gearbox, oil and a bowl. Unfortunately, it still happens to it when stationary or very slow rolling, shifting to P gear when the engine is warmed up

[@GaryFerraro]

A couple of times when i read about those codes, the fix seemed to be a valvebody. Trans is full of oil correct?

[@pawep5571]

@@GaryFerraro The oil level is correct. I'm wondering why the problem occurs only after warming up? Do you think it's a tcm failure or a lack of pressure? I read the adaptive values. They are very good apart from the C brake which is 350mbar.

[@pawep5571]

A new symptom appeared or it was already there, but I haven't accelerated the car harder in a long time. During stronger acceleration 'gears fall out' (revs increase). Then the gear indicator goes out for a second and when I release the accelerator everything returns to normal. Today I disassembled the mechatronic and will send it back to be checked under pressure, but I'm afraid that the problem will be the gearbox.

[@KDanio]

hey, i have a question. the tiny black balls. where do i know how many balls i need and where do i need to place them? i think 1 ball fall out while dissassambling. can you help me ?

[@GaryFerraro]

each valvebody is different, maybe send me a picture of the valvebody [e-mail]

[@KDanio]

@@GaryFerraro thanks, i send you an email :)

[@TheProsparity]

Excellent

Great work...

Thank you Dari

Where i can buy the Rubber dampers for mechatronic unit ? Thank you and great job there !

[@victormorales2052]

Hi. Hello, thanks for your videos. I looked at your tutorial I repaired the transmission of my bmw (6hp21) but it has a detail when I stop at a stop sign I feel a blow when it falls in first gear, I think it is in the mechatronic. Can you guide me to replace? Thanks again for your videos, they are excellent.

[@victormorales2052]

It's feel like a car hit me when stop

[@GaryFerraro]

@@victormorales2052 Reset the shift adapts

[@victormorales2052]

Thank you for you response. 👍🏻

[@Archerthestrangeguy]

hi my 2006 bmw x5 has same transmission. It had 2-1 or 1-2 jerk when hot only. Had bridge seal and sleeves replaced. Doesn`t help. Is that a solenoid problem?

[@GaryFerraro]

I traced this back to either a solenoid or bushing problem, i would do the solenoids first, How many miles on the car? After solenoid replacement, shift adapts must be reset or trans will work the same way, can you reset adapts?

[@Archerthestrangeguy]

@@GaryFerraro thanks for the reply. my car has 230,000km on it. The fluid is not that dirty or burnt smell when i drained it. And it was perfect fine until i reset the adaptive value.

[@GaryFerraro]

@@Archerthestrangeguy If it was good before, drive for a couple of days see if it adapts. The trans will not adapt if transmission or engine codes are present. Trans temp also has to be at least 130F

[@wzrd__3262]

I have a 2008 bmw 335i with a “4F89” code that that’s says “EGS: ratio monitoring, gearshift 3-4” what do you think would possibly be the fix for that? Your feed back would help a ton thanks

[@GaryFerraro]

OK, first has the fluid level been checked?

[@wzrd__3262]

Yes I’ve replaced pan, fluid, sealing sleeves bridge seal and plug adapter, should I have reset adaptations afterwards with a scan tool?

[@GaryFerraro]

Jonathan Ocampo Ok. There is a problem with the E clutch. This clutch is on in 4th 5th and 6th. So either you have a solenoid problem or a worn out rear stator bushing.

[@wzrd__3262]

Gary Ferraro thank you for the feedback! Just bought a solenoid kit, I hope it does the trick!

[@jamesf9074]

How much should I expect to pay for all that hardware as a DIYr? My 2009 X5 is getting some shudder when pulling away on a hill when hot. I don't really want to just throw parts at it, but if the price is right I'll redo the valve body like youve done here.

[@GaryFerraro]

Solenoids came way down in price, the set maybe 400.00 or so, plate around 85.00, other small parts are cheap. Where are you located? do you have any codes in the trans?

[@jamesf9074]

Gary Ferraro I’m in TN. Haven’t scanned for codes, but no errors on dash.

[@GaryFerraro]

James Fisk ok. I would also check the fluid level. The connectors like to leak

[@jamesf9074]

Gary Ferraro finally got to checking the level and it seems good. Forgot to take a pic of the data plate while I was under there. Issues are becoming more frequent. It now how a stutter in town. But if you get on it and load the transmission down, it doesn’t seem to slip. I think I’m going to change the fluid and do the valve body rebuild. I figure I can handle that work fairly well, and if the issue continue I can put the refreshed valve body into a lower mile donor transmission should that become necessary.

[@GaryFerraro]

James F How many miles on the car?

[@ludak83]

Your videos are great, but if you had a better camera they would be near perfect.

[@GaryFerraro]

Will look into that, i upgraded my computer and i am uploading in HD.. Thanks for the tip and thanks for watching
