I noticed My 05 FX 35 not moving as relative to acceleration, sometimes jerk into high gear as i ease my acceleration.
Visited a Gear repair shop, who Ran diagnostic and found these codes P1769, P1764, P1754, P0745 P1815, P1716.
All codes are electrical relating to the TCM.
But on openeing the gear box the Mechanic said the Gear Box drive train is burnt. What could be responsible for the burnt even when there is oil the box?
I will appreciate any idea and clue to this before i tell him to do any thing future.
Do i need to replace the complete Gear Box if yes where can i get a dealer in Nigeria?

Thanks.

Just did this on the wife’s 05 FX 35 with 170K miles. Transmission mechanic said age. Torque converter started shedding material into pump and oil and valve body. Pump cleaned up and wasn’t replaced. New torque converter, new valve body with solenoids, new TCM, reflash, new filter, new oil: $3500.00. Runs like new.
