The Muncie was the top high-performance manual transmission GM \noffered in its muscle cars of the 1960s and early 1970s. It was installed \nin the Camaro, Chevelle, Buick GS, Pontiac GTO, Olds Cutlass, and many \nother classic cars. Many owners want to retain the original transmission \nin their classic cars to maintain their value.Transmission expert and \nveteran author Paul Cangialosi has created an indispensible reference to \nMuncie 4-speeds that guides you through each crucial stage of the rebuild \nprocess. Comprehensive ID information is provided, so you can positively \nidentify the cases, shafts, and related parts. It discusses available \nmodels, parts options, and gearbox cases. Most important, it shows how to \ncompletely disassemble the gearbox, identify wear and damage, select the \nbest parts, and complete the rebuild. It also explains how to choose the \nideal gear ratio for a particular application. Various high-performance \nand racing setups are also shown, including essential modifications, gun \ndrilling the shafts, cutting down the gears to remove weight, and \nachieving race-specific clearances. Muncie 4-speeds need rebuilding after \nmany miles of service and extreme use. In addition, when a muscle car \nowner builds a high-performance engine that far exceeds stock horsepower, \na stronger high-performance transmission must be built to accommodate this \ntorque and horsepower increase. No other book goes into this much detail \non the identification of the Muncie 4-speed, available parts, selection of \ngear ratios, and the rebuild process.","brand":"CarTech","offers":[{"title":"Default Title","offer_id":31911892090951,"sku":"B04437","price":27.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0057\/9813\/3831\/files\/dd304776-09c3-4f38-b88d-10ff7c659bb4_2e90c_8d2fae9c-ae11-4c40-91a2-1cd7608dcccd.jpg?v=1772255096","url":"https:\/\/www.midlifeclassiccars.com\/bs\/products\/muncie-4-speed-transmissions-how-to-rebuild-modify-sa-design","provider":"MidlifeClassicCars.com","version":"1.0","type":"link"}
