1949-1950 Lincoln Hydra-Matic Manual

This illustrated booklet covers the GM-built Hydra-Matic automatic transmission as fitted to 1949 and 1950 Lincoln cars. It opens with a cutaway of the torus, front and rear planetary units and reverse planetary, then the driver's operating instructions for the N, Dr, Lo and R selector positions. No publisher is named; its cross-references to a Thompson repair and tune-up manual suggest it was an aftermarket supplement.

Shop procedures include fluid level checks and drain-and-refill, manual and throttle linkage adjustment (with the change at engine No. 9EL-68809), external band adjustment with tool J-2681 and pan-off adjustment with gages J-1693 and J-5071, valve control assembly removal and overhaul, the governor and rear oil pump, front and rear servos and accumulator with spring free lengths, the reverse anchor and shifter bracket shims, and transmission removal and installation with torque figures. A trouble diagnosis section explains the road test and stall test and lists complaints such as erratic shifts, slipping and no reverse with correction steps. It suits owners, restorers and mechanics working on early Lincoln automatics.
