How it works
A drop-in USA-made hardened steel TCC relay boost valve and bushing restores hydraulic circuit integrity on type two, three and four valve bodies, except some Lexus models. It replaces the soft aluminum OEM assembly, which is prone to wear.
With the included optional low hold 1-2 shift valve, the transmission stays in low gear with the lever in manual low.
It corrects, prevents or reduces soft shifts, burnt clutch plates in hot rod and work truck use, and TCC slip and overheating on type two, three and four valve bodies caused by wear at the lock-up relay valve.
