B&M's ShiftPlus electronic shift improvers use vacuums or electronics to improve the characteristics of your transmission, and let you change settings as you drive. Great for performance, towing, and RV use, these shift improvers recalibrate your transmission in one of two ways: Vacuum-style transmissions, such as a GM 4T60E, simply recalibrate the hydraulic system through the modulator circuit to provide firmer, more positive shifts; electronically controlled transmissions, such as a Ford AODE, recalibrate the transmission's hydraulic system electronically to give you a firmer, quicker shift, for better performance and longer transmission life. A flip of the switch allows the transmission to operate in the original factory mode at level 1 (firmer than factory) or level 2 (much firmer than factory). Either type installs in minutes with a few simple hand tools, without removing the pan.

TCI Trans-Scat valve body kits offer you two options: you can either have good, solid shifting that's well suited to towing, or you can have competition-style shifting. These kits eliminate slippage and lag, improve fuel economy, extend clutch life, and really improve the 2nd and 3rd gear shifts. In addition to delivering crisper shifting, they allow you to downshift on demand, and most will allow you to hold first gear for extended periods, such as when climbing long hills while towing. All kits give you the full range of normal automatic functions when in "drive."
