Tool Kit for 34994-18K
Price: $689.18
Part Number: TAT-F-34994-TL18-SX
Some vehicles with a 4L80-E transmission may exhibit the following problems: converter shudder, burned converters, no TCC clutch apply, and/or code 68/39 or P1870/P0741. Often these complaints can be caused by the constant oscillation of the steel TCC regulator valve wearing the aluminum bore, resulting in a loss of converter apply oil pressure. Sonnax now offers this valve and sleeve kit 34994-18K to repair bores that cannot be refurbished with the teflon seal version 34994-01K.

Features & Benefits

Hard-anodized aluminum valve and highly wear-resistant aluminum alloy sleeve prevent further wear.
The valve spool land at the spring end has been lengthened to provide greater bore-to-valve surface contact, thus further preventing leakage.
The heavier spring provides OEM lockup feel. The lighter-duty spring provides a firmer lock-up, best suited for towing applications.
The valve spool has annular grooves to help center the valve in the bore.
The aluminum sleeve provides significantly more support and contact area with the valve to prevent wear and leakage.

You need this if...

Bore wear is extensive in the seal contact area.
