paragraphe CH2 : 5
"Solenoid Valve SL1 and SL2
During a solenoid valve SL1 or SL2 malfunction, up-shifts to 5th and flex
lock-up clutch control are prohibited"
CH5 :
"Solenoid Valve SL1, SL2, SLT, and SLU are used by the ECM to control hydraulic pressures in a linear fashion based
on the current that the ECM causes to flow through their solenoid coils. They control line, clutch, and
brake engagement pressure based on the signals received from the ECM.
The solenoid valves SL1, SL2, SLT, and SLU have the same basic structure."

Function of Solenoid Valve SL1, SL2, SLT and SLU
Solenoid Valve Function
SL1• Clutch pressure control + Accumulator back pressure control
SL2 Brake pressure control
SLT • Line pressure control + Accumulator back pressure control
et sur ce lien j'ai trouvé l'emplacement sur le valve body :
chaque valve est détaillée chez toy:

la ref de la platine :
35410-60520
je ne sais pas si elle est livrée complete avec toutes les valves neuves, ca pourrait valoir le coup à moins de 1000 dollars (hors port / douane)...

mais comme à dit Pat25, déposer les valves, les nettoyer et si ca se trouve ca repart direct!
