Description

#5R55EPV. Some typical problems in 4R44E, 4R55E, 5R44E and 5R55E units are soft shifts, delayed reverse, poor modulator control and / or low line pressure in reverse. A worn boost valve is often the cause, allowing reverse and / or TV pressure to cross leak or exhaust. Sonnax now offers a replacement boost valve kit for these units to increase the ratio for slightly higher line pressures. (stock size)
