Cooler Bypass Valve Kit - E4OD/4R100
Price: $19.99
Part Number: TAT-S36996A-5K-TS
Sticking of bypass components, spring relaxation or poor ball seat will allow the bypass to open at lower cracking pressure. This reduces TCC apply pressure, cooler flow at the overdrive section, and radiator flow responsible for heat transfer. The Sonnax kit allows the bypass valve assembly to be rebuilt and maintains cracking pressure at 70-75 psi.

Features & Benefits

Hardened steel T-valve provides secure checkball seat and adequate bypass flow.
New spring cracks open at 70-75 psi to provide lube if cooler is blocked or restricted.
Hardened alloy steel checkball resists damage.
Seven new o-rings provide positive seal for cooler circuit.
Allows salvage of the OEM fittings.
