Started having issues with my auto trans back in November, after doing some research i thought i could get away with just replacing the mechatronics seals the 4 tubular seals, the bridge seal, and the electrical connector seal. after re assembly this did not change the shifting and was still having the issue. then i bought some solenoids, re assembled again. I put a new pan on and Liqui Molly ATF, and reset the adaptations through INPA, it drove perfect for two weeks but it got worse over time, it would hit neutral points when shifting from first to second and then slam into second gear really hard, it would always stop in second gear at a light and frequently would not want to go into first and in auto would keep trying to downshift and would slam into gear and lurch the car forward pretty hard. it also did not want to go into 6th gear at all and would take many attempts with steptroinc going from 5-6 failing and repeating till it finally went into gear. Also their was a wining noise coming from the trans tunnel under acceleration in higher gears from low rpm originally but was resolved with the solenoids and haven't had the issue again.

I bought a used transmission with 76k miles for $300 and just swapped over the valve body unit and pulled my old TCM, put a new pan (again) and fluid and filled 3 times with the car running and shifting through the gears to make sure fluid level was correct. The car has been shifting perfect until 3 days ago, i am now experiencing a "neutral" state again between 1st and 2nd gear and will eventually slam into second but will shift perfectly from gears 2-5 afterwards. along with the 1-2 it will also also fail to shift into 6th and fall back into 5th and show a trans malfunction error as it was doing before the valve body swap but is a lot more forgiving than before and will usually go into gear after one or two attempts with a shift flair.

It is no longer having issues going into first gear, but i am periodically getting the issues with 1-2 shift and 5-6 shifts, i briefly had a 3-2 error but i haven't been able to replicate it. I did not reset adaptations after the valve body swap and after about 30 minutes in a parking lot stopping and going from 1-2, 2-1 it stopped slamming into gear and would just flair the shift. The first problem since the valve body happened when i was driving on snowy roads and it started to start in second gear ( not sure if this is normal ) and threw a trans malfunction for the first time since the new valve body.


Really confused at what exactly my issue is, clutch packs would make the most since, but both times I've had this issue its perfect for a week or so then gets WORSE OVER TIME, and will drive completely fine once you cycle the car and turn it off and on again, it will drive fine and shift from 1-6 and back from 6-1 no problem but periodically it bugs out it will then start slamming into second and not want to go into 6th. ( it will work fine thorough many stops to first gear but will eventually start having issues.)



Also was considering getting xHP and trying the pressure line bump feature that allows more pressure for controlling the individual clutch packs.

my codes are
004f83 EGS: Ratio monitoring clutch C
004f8b EGS: Ratio monitoring gear shift 5-6
004f8f EGS: Ratio monitoring gear shift 1-2
004f8f EGS: Ratio monitoring gear shift 3-2( haven't had this one come back)
