Transmission trouble

Hi Everyone

I have a 2000 CL600 with 265 000Kms. The car is as new, and very well maintained.

Recently, I have run into problems with the transmission. The car will not shift out of second gear into third. I can feel it shift from first to second.

I have scanned it and have the following printout:

110 - The speed comparison of Y3/6n2 to Y3/6n3 is sporadically implausable. (Resistance too low)

116 - Component Y3/6s1 (Starter lockout contact) or component Y3/6b1 (Transmission oil temperature sensor) is sporadically faulty or both. (Resistance too low)

146 - The transmission has sporadically an impermissable transmission ratio. (Resistance too high)

147 - The gear is sporadically implausable or the transmission slips sporadically. (Resistance too high)

151 - the gear comparison is sporadically negative or the target gear has sporadically not been achived. (Resistance too high)

I have access to a workshop, so I would like to tackle this on on my own, and provide pics of the procedure. Any asistance with this matter is most welcome.

Agreed that it is the conductor plate. Same issue (different verbiage) on my W140 with the same 722.6 transmission.

PS - while replacing the conductor plate, I would also replace the following:

TCM Connector Plug/Bushing!!!!
ATF Fluid, Filter and Pan Gasket
ATF Cooling line to the radiator.

You may have to connect the car to a Star Diagnostic System to clear the codes after replacing the conductor plate.
