Transmission Parts Toyota/Lexus A340E A340F Valve Body End Plug

Symptoms:

Soft shifts
Low line rise
Slips & flares

Cause:

Valves, springs and pressurized fluid repeatedly push on the end plugs causing the plugs to deform and wear. As a result, critical pressure is lost due to excessive clearance between the plug and bore.

Correction:

Sonnax drop-in O-ringed end plugs restore correct circuit pressures. The O-ring provides additional sealing to reduce pressure losses past the end plug.

In Toyota A340E and A340F late units, valves, springs and pressurized fluid repeatedly push on the end plugs causing them to deform and wear. As a result, critical pressure is lost due to excessive clearance between the plug and bore. Sonnax O-ringed end plug kit 97741-19K restores correct circuit pressures by positively sealing to reduce pressure losses past the end plug.
