Your gear position sensor harness insulation is probably falling off & wires are touching. I’d pull the trans & re-rap all the wires individually & check previous work. I’ve never herd a smg pump prime that long & reach such a low rpm as if it was struggling. Good luck.
I replaced the transmission with a used unit. I can only guess that the issue was the solenoid assembly that sits on top of the transmission which is silly money to replace, cheaper to buy a used SMG transmission

I have the same code on my m5 as well but it doesn’t grind and shifts perfectly fine. When I drive it hard then the transmission light comes on and wouldn’t move for a bit then drives fine I also have a code for the pressure sensor , could that be my issue ?
Did you test the accumulator pressure ? On my side, I've got the same noise, but the problem is due to first gear lock. Impossible for me to switch to another gear or on neutral... I tried pump pressure, it's ok, accumulator pressur, it's ok. I've got problem with solenoide clutch learn, i've got a message "exceeding the time allowed when finding the crossing of the valves'. Keep searching !
Here is what is interesting, when the pressure is on the higher side it works fine, but for whatever reason the pump either cannot keep up or something and once the pressure drops after a shift or two its stuck. I actually have another E60 M5 with a working SMG transmission. I am going to swap accumulators and see if that fixes it 1st
@@macoh3115 If the pressure is going down to fast, so the accumulator could be KO, if you have ista/rehingold, you can trying the pressure of the accumulator to check this one.
@@macoh3115 bro the reason, you mentioned in the video , that you serviced everything , these units have extreme pressure , the who serviced it ,he destroyed the original solonoide valve seals behind the pump , only a new unit can solve it, or a highly trained staff
I think I have same problem as you do. I changed electric motor, pressure sensor and relay none of which fix the problem. The issue is that my hydraulic unit not able to build enough pressure. Have you find a fix?

So mine was working perfectly fine. But leaked from the slave, took it to a shop to have that replaced. The shopped messed up my gear selector harness and threw out some codes now replacing that harness and it says 1/r redundant so might do the actuators but im sure mine is just the harness. Just bought a complete smg unit from a guy who seems to only have pressure issues. What codes is that one throwing? Lets link it to a specific part and i can see if i have that spare part and could have it shipped to you. I got the trans as a spare from a paint job deal. The spare smg unit i paid 600$ came complete from a 75k mile car so it should be good
No, that wasn't it. I put a new pump on it and had the same issues. I replaced the transmission with a used unit. I can only guess that the issue was the solenoid assembly that sits on top of the transmission which is silly money to replace, cheaper to buy a used SMG transmission
@@macoh3115 did you check the wiring harness? I had a friend who had the wiring harness insulation disintegrate and he had to replaced it because of that , these seem to be a common problem, worth checking out.
@@macoh3115 sooner or later you need to fix it and surprisingly the clutch on these fast worn out even with low miles and the flywheel need to be change also.
@@macoh3115 This may be late but it's always welcome to me when I get some closure on this type of thing. The first red flag was the pressure drop. It's a sealed, pressurized system. Losing 5psi in seconds is excessive unless it's a relief setting, and you can check that by watching the pressure over a period of time. If it is a leak you're probably looking at the accumulator unless you can find an actual hydraulic leak in the lines or actuator. If it's none of those things the pump is likely the culprit. Ultimately it is the pumps job to keep up with system demands, the accumulator provides supplemental (reserve) pressure for operation when the pump isn't operating. This should help, or at least I hope it does. Good luck, SMG's are a patient mans project..
Try pumping it up and doing the second gear change instead of first then second and see if that works. If it does then that pressure loss is not normal (and I don't think it should be) and you have a leak somewhere or through some seals internally. Do you still have the car? EDIT: Actually the pump was running during the second gear change so its gotta somehow be leaking somewhere when you're going into second. Try the rest of the gears hopefully its only on second gear maybe you can isolate the pressure loss.

BMW should repair all SMG cars for free as it is a major recall defect they ignored for past decade.
I have the exact same issue currently on my M5 E60, any update on how u resolved ?
Please can help me

you slow slow slow puppet, listen to me the whole smg unit never fails ! its the seals that go. i own 2 of these gems i know @@mkks8023
my SMG doesn't go into reverse and immediately puts it in second gear, puts it back in first gear, but stays in second gear and the car won't drive.
