Sonnax pressure switch rebuild kits can help salvage your transmission electro-hydraulic control module (TEHCM), restore normal switch operation, eliminate codes, and provide renewed shift performance in all ranges. Some GM transmissions send various trouble codes related to internal fluid pressure failures to your TEHCM. These codes may be accompanied by torque converter clutch (TCC) apply problems or shift irregularities such as slipping, flares, harsh application, and bind-ups. Often, the cause is laminated portions of unobtainable OE pressure switches breaching, preventing normal switch operation. Avoid multiple breakdowns that can trigger failsafe mode and TEHCM replacement by ordering the Sonnax pressure switch rebuild kit recommended for your GM transmission.

Solenoid switch valves and plugs in various Chrysler transmissions cause bore wear as they oscillate and stroke during operation. This wear allows pressure loss and cross-leakage, and often permits the plugs to cock and hang up in the bore. This can result in failsafe mode, various codes, bind-ups, and burnt overdrive or 4th clutches. In 41 and 42 series units, TCC concerns can result, including engine stalling due to improper lockup. Reconditioning the bore and installing a patented Sonnax oversized solenoid switch valve and plug kit restores vital clearances for renewed operation and control. Additional details: * Patented Sonnax plugs redesigned to prevent cocking * O-ringed end plug positively seals bore * Annular grooves help center valve and plugs in bore to prevent future side-load wear * Hardcoat anodized aluminum valve and plug combat premature wear * Fits bores containing OE switch valve with .453 in. diameter large spool only Kit contents: -- Valve -- Inner plug -- Outer plug -- End plug -- O-ring

ATP pressure switch manifolds (PSM) are assemblies made up of multiple pressure switches. Fluid pressure is directed to the switches depending on the position of the gear selector and the manual valve. The fluid pressure determines digital logic at the electrical pins on the PSM, which is used by the vehicle's Power Control Module or Transmission Control Module to determine what gear range the transmission is operating in. ATP pressure switch manifolds are manufactured to meet or exceed OE standards—and are vital components for your automatic transmission rebuild.

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.

RevMax billet high performance towing/HD valve bodies for a variety of applications, including many Dodge and Ram trucks from the early 2000s and up. The V2.0 is 1 in. thick, but this new version has precision cutouts that allow the use of a stock filter and pan. Unlike other designs, full depth worm tracks in crucial circuits are included. Other competing designs have only a .190 in. deep worm track in several critical circuits. One restricted circuit is the combined vent track, responsible for all venting operations and in particular the problematic SSV valve. The next restricted circuit is the torque converter clutch signal circuit. Restrictions in this circuit create all kinds of torque converter related concerns, including dragging when coming to a stop, overheating, soft or harsh TCC apply or release, and back feed issues resulting in P1776 and P0871 trouble codes. Both the original and V2.0 have nearly full depth worm tracks in these areas which eliminate problem issues! The V2.0 plate will work with ANY aftermarket transmission pan, as well as with stock transmission pans. There is no need to alter any part of the pan or use special filters. Just install it like you would a stock channel plate and go. Order the model recommended for your year/make and transmission application. The RevMax 68RFE V2.0 ZeroFlex billet valve body features the following: * 6061 billet aluminum construction * Deep critical worm tracks * .0003 flatness across the entire plate. The only truly flat billet channel plate! * Micro-polished worm track surface. There are no visible or perceptible machining marks or stepovers. This ensures no chance of any leaking due to machining marks * Large radius machining on the filter cutout increases rigidity yet allows the use of a stock filter assembly * Angle milled step downs increase rigidity in problematic flexing areas * Ability to run up to 325 psi of line pressure without any warpage! (transmission tuning, TCM upgrade or pressure box is needed) * No pump modifications required for up to 250 psi * Proprietary worm track layout * Shortened shift times for crisp, clean shifts * Upgraded valve body to case seals * Billet steel SSV solenoid switch valve and end plugs * Revmax triple double 3/2 billet accumulator pistons with dual seals * Upgraded grade 8 custom fasteners * Upgraded steel accumulator housing plate that is 3x thicker than stock * RevMax proprietary accumulator springs for improved 3-4 shift feel * RevMax proprietary separator plate with the bonded gasket that eliminates cross leaks and warpage issues * Revmax proprietary upgrades * Mounting surface verified and flat filed * Threads checked and repaired if needed * Computerized testing on state-of-the-art $125k valve body test machines
