HI!
i havent posted in long time cause im pretty good with the forum and the knowledge given from members to diagnose things myself (i.e. cps and bad maf) but i think im on the verge of needing something dealing with the transmission. so the only things i have had to replace on this car is the power steering pump, the cps,maf,and idler pulley. this car has been AMAZING and always puts a grin on my face when it still surprises me. the only mods are a mercedes sl airbox and 74mm tb and secondary cat delete. 275/35/19
recently i have noticed the car has been jerky while upshifting to the point where it is embarasing. low speeds like turning onto an onramp from a light and needing to merge quickly type situation. lots of drone which i know this car is small and all that but ive been reading a lot on the faulty valve body/conductor plate and how almost everyone has had to change this sensor around the 100k marker.
i have no codes and i have never taken it in to be "read" by the dealer. also i have yet to change the 02 sensors. it doesnt seem to run rich but i know not much about cars this little beast has been a great learning experience.
anyways, my question is should i change the valve body before a code is thrown seeing as how the sensor will fail, or should i get an obdII reader and see if there is any hits from the control modules in the car. also! if i decide to replace the conductor plate without a cel will i still need to have it reprogrammed/reset by the dealer in order to be operable.
sorry for the rant its just i will be looking to seek action by the end of the month cause i really dont want to mess around when it comes to the transmission, also i should add there has been a "rear seal weep" since i bought the car and surely that is messing with the electrical connector.

 

Are you leaking any transmission fluid? You may want to check THIS and see if that could explain your transmission issues.
