It is economically feasible to rebuild almost any Brinn transmission. If your local Brinn dealer or distributor does not offer this service, it is available from Brinn Incorporated direct. The Brinn shop rate is $50.00 per hour and a typical off-season freshening runs between $250.00 and $400.00. Extensive parts replacement would drive the cost up, however. Specific estimates are available upon inspection. There is no charge for an estimate if the work is performed.
