B\u0026amp;M® Transpak™ kit for 1982-1993 GM TH700R4\/4L60 automatic transmissions. Most stock automatic transmissions won't downshift into low gear above 15 mph, and automatically upshift at a predetermined speed no matter what gear you're in. With the Transpak, you can downshift at any speed, and you can hold the transmission in first gear to any speed that you want! This is an asset when you've got a modified engine, and you want additional RPMs, or you're towing a trailer or driving heavy loads downhill. Stage 1. Heavy Duty is for street rods, normal passenger vehicles or other heavy duty use. Firmer shift feel but not harsh. Improves transmission performance and life dramatically without loss of comfort and offers normal automatic operation when in Drive. Stage 2 is for Hi-Performance street use. Essentially the same as Heavy Duty mode except shifts are much quicker. Retains full automatic features and standard shift points with selector in Drive. Note: Not for GM 4L60E electronic transmissions.","brand":"B\u0026M","offers":[{"title":"Default Title","offer_id":55196056420520,"sku":"BBFT_70235","price":204.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0402\/2344\/1064\/files\/70235.jpg?v=1768806720"},{"product_id":"fits-1997-2015-gm-models-2wd-automatic-shift-valve-body","title":"Fits 1997-2015 GM Models - 2WD - Automatic Shift Valve Body","description":"Built for serious power and weight, this Street\/Strip 4L80E features a 34-element intermediate sprag, high-energy band, new overdrive sprag and low roller assemblies, performance frictions, recalibrated valve body, performance pump, steel forward hub, and all-new solenoids\/harness for crisp, durable shifts.
