Hello Edmundo, in the 4M40T of those years the regulation of the Kick Down cable is simple you leave a little free game at rest. On the TPS, on the axis of the imjection pump is what is causing the rare pattern of change observed. The voltage of the TPS with the lifted foot (idle or minimum) must be 0.85 volt, (+/ - 0.2 v). The TPS signal goes to the control module of the Transmision (TCM) and you can regulate it by releasing the 2 pernitos that hold the TPS to the pump, turning it slightly. The ideal you use an electrical tester to measure the voltage and be able to regulate it. In the TPS connector you are going to see 3 cables, with the disconnected plug and the on the on on measure voltage by the 3 pins. 1 It should mark you 5 V (reference), another zero V (mass) the third must mark a slightly lower voltage than the 5 V reference (approx 4.7) and this is to be the signal, which is the important one to measure to regulate the TPS. I recommend regulating it with the engine walking, the vibrations affect the TPS if it is loose. I have enough experience in 4m40s in Monteros and Delicas and with 0.85 V in idle in the TPS, those vico ones fly ... greetings from Chile.
