Bore wear or a stuck converter feed limit valve in GM 8L45/90 transmissions can result in converter overheat, incorrect TCC apply or release, inadequate lube and cooling, and converter over-pressurization. Reaming the bore and installing this new Sonnax kit will recover hydraulic control, renew TCC and lube performance and protect against premature wear for lasting results.
