PFF76-923 Upper Gearbox Mount Insert is an affordable and easy-to-fit bush insert made from our Yellow 70A Durometer vibration-absorbing material, which works to stiffen the OEM upper gearbox mounting. This reduces twist of the engine under acceleration and during gear changes, giving the pedals a more direct feel, as well as reducing wheel-hop and letting you get the power down that little bit quicker. We recommend fitting PFF76-923 alongside our other Yaris GR powertrain inserts (PFF76-920 & PFF76-925), as they perform much more effectively as a full set. There will be a minor increase in NVH when stiffening the powertrain mountings.
PFF76-923 is made from our Yellow 70A material and works by stiffening the OEM powertrain mounts reducing the amount of engine/trans roll and movement during hard acceleration and gear changing for a more responsive feel.
Fitting Instructions:
1. Support the gearbox from below with a jack or
axle stand.
2. Remove the gearbox mount from the car.
3. Loosen and remove the bolt securing the
gearbox supporting post to the bush (Figure 1).
4. Slide the post and it's rubber insulator out from
the bush/bracket assembly (Figure 2). Some dish
soap may be used to lubricate these parts and
ease disassembly.
5. Fit the insert onto the Rubber Isolator, as shown
(Figure 3)
6. Push the bush/bracket assembly into the insert
(Figure 4), and make sure the rubber flaps seat
correctly around the bush sleeve inside the
vbush/bracket assembly.
7. Push the post back into place inside the rubber
isolator (Figure 5), and fasten it to the bush with
the bolt, and tighten to manufacturer's
recommended torque spec.
8. Refit the mount to the car, and tighten all
fasteners to manufacturer's recommended
torque spec.
