From a closed GM dealership . . . . . Allison LCT 1000 Automatic Transmission Diagnostic Close-Up Training Manual, a GM training manual used by service technicians, published by General Motors Corporation in 2002, used, spiral bound, contains information for this transmission and includes great pictures with exploded illustrations, plus much more. The Allison LCT 1000 automatic transmission was offered in the 3/4 and 1-ton pickup trucks. However, not all trucks in these weight categories will have the Allison Transmission. This transmission was only offered with the 8.1L gas engine and the 6.6L Duramax diesel engine. The only exception is the 3500 HD that uses the previous style cab (C/K) which offered the 8.1L engine, but uses the 4L80-E. Great manual to have if you own or are rebuilding one of these units!
