The P310 eCVT transaxle is a massive unit weighing in at 287 pounds. It uses a damper plate assembly instead of a torque converter between the transaxle and the engine. (Figure 17)


ATSG Ford Escape Hybrid Preliminary Information - Figure 18

There is a high voltage warning tag on the transaxle top cover because the DC to AC Inverter as well as the Motor Control Modules are located underneath the cover. (Figure 18)


ATSG Ford Escape Hybrid Preliminary Information - Figure 19

These are most of the connectors that have to be disconnected for transaxle removal  which are the TCM, MECS and HV cables.(Figure 19)

Located between the MECS coolant pipes is the Hybrid System Temperature Sensor (Figure 30)

The top cover is ready to be removed; it has been damaged due to improper handling. This must be avoided due to what lies underneath this cover. (Figure 21)


ATSG Ford Escape Hybrid Preliminary Information - Figure 22

Below the top cover is the DC to AC inverter, care must be taken not to damage this due to mishandling. A ground strap should be worn to avoid electrical damage from static electricity. (Figure 22)


ATSG Ford Escape Hybrid Preliminary Information - Figure 23

Once the inverter has been removed this cast aluminum cover is next. All the bolts are mounted in rubber grommets, make certain during assembly they are all in place. (Figure 23)


ATSG Ford Escape Hybrid Preliminary Information - Figure 24

Be sure to disconnect all six ground straps before the cover is removed and make certain they are all reattached during assembly, there are two on each side and one on each end. (Figure 24)


ATSG Ford Escape Hybrid Preliminary Information - Figure 25

Handle this cover with the same care as the inverter because the TCM is located on the under side (Figure 25)


ATSG Ford Escape Hybrid Preliminary Information - Figure 26

Once the TCM cover is removed, the capacitor pack can be removed. There are three capacitors rated at 450 volts and 125 amps each, they will not fall out of the cover when it is removed. (Figure 26)

Underneath the capacitor pack is where the Generator Control Unit (GCU) is located. It is rated at 300 Amps. Next to the GCU is the Motor Control Unit (MCU). It is rated at 600 Amps. These two modules control the operation of the Generator Motor and the Traction Motor which is the larger of the two. (Figure 27)

Once the module assembly is removed this cast aluminum plate will be visible. It covers the transaxle cooling chambers. (Figure 29)


ATSG Ford Escape Hybrid Preliminary Information - Figure 30

Coolant is circulated by the MECS pump which keeps the GCU and the MCU from overheating. (Figure 30)

The lubrication pump is a simple gerotor style, with a pressure regulating valve. The sump filter is bolted to the pump and is readily available. (Figure 34)

In the transmission case where the Generator Motor and the Traction Motor bearings are located, there are end play shims that must be installed in their proper locations. Measure each one during disassembly so the correct thickness shim goes in the correct location. (Figure 36)
