TCI Replacement Steel Transmission Pans

TCI steel transmission pans are the perfect replacement for performance and appearance beneath your vehicle. These steel reservoirs are thicker than stock for longevity, and some models are beautifully chrome plated to further prevent rust—in addition to including a drain plug to facilitate fluid maintenance. Over time, many transmission pans develop a warped, leaky gasket flange, or become damaged by road debris. Protect your transmission by bolting on one of these economical replacement upgrades from TCI.

Pacific Performance Engineering Transmission Fluid Bypass Valves

Pacific Performance Engineering offers automatic transmission fluid bypass valves for a variety of applications. The OEM part has restrictive internal passages; and when the OEM valve fails in the open position, transmission fluid doesn't reach your cooler. This can be caused by mechanical failure or debris. The result of stock valve failure can cause the transmission to dangerously overheat. Without properly cooled transmission fluid, the demands of towing and rigorous stop-and-go driving conditions shorten the life of transmission components. This PPE bypass valve eliminates the mechanical valve—which maximizes fluid flow from the transmission cooler. For further protection, a Neodymium magnet-equipped service plug has been added. The removable plug traps ferrous debris and can be accessed to remove particles from the system. The factory part does not have this feature. Additional notes: * Billet aluminum construction * Neodymium magnet-equipped service plug with O-ring * Easy to install * Limited lifetime warranty

ARB Differential Breather Kits

ARB differential breather kits are important to vent air pressure in drivetrain assemblies, and they eliminate the shortcomings of your factory breathers—especially when driving through water crossings. ARB units are high-flow, zero backpressure, zero vacuum breather systems. Each features a high-flow air filter within a central manifold that will allow up to four drivetrain assemblies to be vented to one central location--ideally somewhere on the vehicle that will be above the water level at all times. ARB differential breather kits are intended to replace your factory breathers and contain enough fittings and tubing to connect at least two drivetrain assemblies. Additional features and benefits include: * Axle breather manifold is machined from billet aluminum and anodized, making it lightweight and resistant to the elements * The manifolds have four axle breather ports, allowing for 1-4 breather lines to be connected * Very compact design, allowing them to be installed in virtually any location * The kits come with self-tapping screws, but the manifold mounting holes are large enough to allow mounting using an M6 (1/4 in.) bolt or stud, which is the common size in most vehicle engine bays * The air filters are the ARB compressor air filters, which are splash-resistant with washable high-flow sintered bronze filter cartridges * 8mm polyethylene tubing is flexible, oil-resistant, water-resistant, and heat-resistant * 8mm tubing has been selected over the standard 6mm tubing to improve the airflow and reduce the chance of oil blockages in long breather lines * 8mm push-in fittings make installation simple and fast * Kits include anodized aluminum manifold with 5 ports (breather lines and air filter) and 2 mounting holes, air filter assembly, fittings, plugs, polyethylene tubing, screws, and cable ties

Sonnax Pressure Regulator and Shuttle Valve Kits

Vehicles with a GM 8L45 or 8L90 automatic transmission may exhibit high or low line pressure that results in harsh/soft shifts, burnt clutches, loss of cooler and lube flow, and overheating of the transmission and converter. These problems may be caused by wear of the pressure regulator bore casting at the VFS signal port area and/or at the shuttle valve sleeve. Wear at the inboard port of the pressure regulator bore allows VFS (throttle) signal pressure to leak, preventing proper action of the pressure regulator valve and potentially allowing it to remain in the low line pressure position. Wear of the shuttle sleeve due to continuous oscillation of the shuttle valve creates a path for balance line pressure at the pressure regulator valve to exhaust, resulting in excessive low line pressure. Sonnax drop-in pressure regulator and shuttle valve kits restore hydraulic integrity to the lineup by addressing wear that subjects the transmission to either excessively high or low line pressure with upgraded materials and unique designs. The pressure regulator valve has been designed with a lengthened spring pocket spool at the VFS signal port area, which provides over double the sealing capability to this critical end of the valve and allows it to operate in unworn portions of the bore. The length of the critical shuttle valve diameter has been significantly lengthened to provide better sealing and durability of the assembly. Additional details: * Hardcoat anodized aluminum valves and highly wear-resistant billet aluminum sleeve combat premature wear * Pressure regulator valve VFS signal spool 200 percent longer than OE and operates in unworn area of the bore * Critical shuttle valve spool made 30 percent longer than OE for added sealing and durability * Drop-in Zip Valve parts install quickly and easily Kit contents: * Pressure regulator valve * Spring * Shuttle valve * Shuttle sleeve

Sonnax Solenoid Switch Valve and Plug Kits

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
