Great for transplants! TransGo Automatic transmission modulator conversion kits provide a more aggressive and tunable pressure boost curve with engine vacuum instead of the vehicle PCM controlling PCS/EPC solenoid. TransGo modulator conversion kits include everything needed to add the internal modulator system with the oil pan off the transmission. From the outside of the transmission, you will need to connect it to an intake manifold vacuum source, however hardware is not provided for this. The kits do come with an oil pan-based resistor to pacify the control module for the missing EPC solenoid in applications where the computer will still manage the gear changes. TransGo includes: * Pressure regulator valve spring and snap ring * Brass fitting * Vacuum modulator, pin, valve, and bushing * Hold-down bracket * Elbow vacuum hose and spring * Four short zip ties * Five long zip ties * Vacuum tee * Resistor

Bowler Performance lock-up control modules come complete with everything needed to seamlessly control your torque converter lock-up. Converter lock-up will occur 8 to10 seconds after 4th gear engagement, allowing enough engine rpm gain before lock-up, giving your engine more performance and providing a better feel to lock-up. Bowler's lock-up modules only require one 2 amp fused 12 V wire to operate. No vacuum switch is necessary allowing these modules to function correctly with all types of engines, and there are no bulky boxes to hide or mount. The control modules have the GM 4-prong connector integrated onto the control board, and are epoxy coated to stay protected against the elements. Choose the kit designed for your transmission. Kits include: * Lock-up control module * Internal wiring harness with lock-up solenoid and mounting studs * Pressure switch * Pan gasket * New transmission filter * Case pass through connector * Brake light switch—standard that has a normally closed switch (for your lock-up module) and a normally open switch (for your brake lights). The brake switch does not have to be installed for the lock-up module to function, but will allow the driver to tap the brake to un-lock the converter at any time. If you are going up an incline and need a few more rpms to get up that hill, just tap the brake, and the lock-up will turn off and not re-engage for approximately 8 seconds. For those with a high-gear ratio and late down shifts who experience a chug of the motor due to the lock-up converter still being engaged; the switch will eliminate this concern.

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.
