    Hard Shift from 4th to 5th gear or a bit delayed despite ATF flush and solenoids replacements

    Update: - I updated the TCM software at the dealership and boom; 90% of the hard shifts are gone! Thanks, Husam

    Hard Shift from 4th to 5th gear or a bit delayed despite ATF flush and solenoids replacements

    Thanks for the detailed approach. Here is the update from my side: - Scan tool shows zero DTCs. - Before I flushed the transmission (the last flush out a total of 4 flushes), I added a solvent to clean/flush the varnish out; turns out the ATF was in a pretty good condition. (Solvent added: BG...

    Hard Shift from 4th to 5th gear or a bit delayed despite ATF flush and solenoids replacements

    Thanks for the pointer -- but I have already ran a complete DTC check on the car and had zero codes. I even erased the AT adaptive values.

    I guess so too. I'll schedule an appointment with the dealership next month to check the SW.

    Hard Shift from 4th to 5th gear or a bit delayed despite ATF flush and solenoids replacements

    I've done that for a couple of times before adding any additives. I performed at last 2 flushes with OEM fluid without additives; the same behavior persisted. Adaptive values have been reset multiple times. The strange behavior is that the hard shift only happens between the 4th and the 5th...

    Hard Shift from 4th to 5th gear or a bit delayed despite ATF flush and solenoids replacements

    Yes, I performed at last 2 flushes with OEM fluid without additives; the same behavior persisted. Adaptive values have been reset multiple times. The strange behavior is that the hard shift only happens between the 4th and the 5th gear while the ATF is not fully warmed up. This is a question...

    Hard Shift from 4th to 5th gear or a bit delayed despite ATF flush and solenoids replacements

    Yes, the first flush attempt was performed without any sort of additives. The strange behavior is only seen when ATF is cold; but once warmed up, it is smooth.

    Hard Shift from 4th to 5th gear or a bit delayed despite ATF flush and solenoids replacements

    I already did this after the 1st flush of the ATF; I used OEM ATF yet the same behavior persisted. Even after all the flushes, I always OEM ATF.

    Shift Solenoids Cleaner additive?

    Shift Control Solenoid Valve C (35R/C) was replaced and the transmission shifts smooth now. However I am considering XADO additive in the next ATF change to repair any worn clutches.

    Shift Solenoids Cleaner additive?

    I already drove over 200KMs with Lubegard. What I just did is - i have a "Launch" Scanner with me anyway - I did a live stream on a few solenoids and here are the screenshots. The culprit is Shift Control Solenoid Valve C (35R/C) which is responsible for 2nd to 3rd AND 4th to 5th shifts. I...
