B&M SHIFT IMPROVEMENT KIT (1993-2006 GM 4L60-E)

Here at B&M, we find the term "slush box" extremely offensive when used in the context of an automatic transmission. If those two words are a fitting description of the shift quality in your vehicle, we are here to help. B&M offers a range of kits that will give your automatic transmission anything from a subtle improvement all the way to that race-car quality shift which B&M transmission's are famous for. B&M's Transmission Kits modify an automatic transmission's shift timing in order to increase shift firmness and in turn improve durability. This is because many OEM's allow far too much shift overlap in their transmissions. With too much overlap comes not only that dreaded, disconnected, "Slushy" feeling when driving, but also decreased efficiency and durability because of excess heat.

With a B&M Transmission Kit, you can reduce this overlap period, which has several benefits: Not only is the shifting action improved, but because less slippage is occurring you can notice improvements in city fuel economy. Finally, with less heat being generated by the transmission itself, there is less stress on the seals and clutches within the transmission, improving reliability.
