Transmission Alignment Tech Tips

One of the more neglected items when assembling a transmission and engine together is the dowel pins that are pressed into the back of the engine block. These dowel pins serve the purpose of locating the transmission correctly and accurately to the back of the engine block. These dowel pins are actually a highly, highly critical piece of hardware.

NEW! TH400 w/Engine Braking!

New TH400 reverse pattern manual valve body with engine braking now available! Hughes Performance is now offering a full manual valve body with reverse shift pattern and full engine braking in all forward gears under part number HP2211EBR for the TH400 transmission.  The reverse shift pattern in this valve body is P-R-N-1-2-3.  This valve body is an excellent choice for off-road applications that can benefit from being able to rapidly cycle from low gear to reverse and back with the reverse shift pattern all while still retaining engine braking in all forward ranges for maximum braking ability while decelerating downhill or on an off-road race course.  This valve body is also ideally suited for anybody with a street car that would prefer a reverse shift pattern but would also like to be able to downshift the transmission under power and/or load.     This new valve body is a direct replacement for virtually any existing automatic or forward pattern manual valve body for the TH400, and easily installs through the transmission pan with no further transmission disassembly required.  Installation of this valve body will also provide you with an ideal opportunity to upgrade to our deep cast aluminum pan available under part number HP2280 as well as install our recommended Lucas Sure Shift (part number HP501) or Lucas Extreme ATF (part number HP503) transmission fluids.  The HP2211EBR valve body is in stock and ready to ship immediately. *Please note that if you are replacing an existing reverse pattern manual valve body then you will need to partially disassemble the transmission so that the intermediate band can be re-installed into the transmission.  We recommend our Kevlar intermediate band available under part number HP2251H.  This band is also included in our premium master overhaul kits for the TH400 transmission.

NEW! Constant Pressure Valve Body!

Hughes Performance is excited to announce that we are now including an upgraded constant pressure valve body in all of our Street/Strip 700R-4 and 200-4R transmissions at no additional charge!  The constant pressure valve body is a superior design that offers clean, crisp shifts along with significantly more consistent shift timing.  The most exciting part about the constant pressure valve body is that the T.V. system no longer has any affect on line pressure.

This means that an incorrectly adjusted T.V. cable will no longer contribute to a premature transmission failure.  With the constant pressure valve body installed the T.V. cable is only used to set shift timing and provide kickdown function.  You can now fine tune your T.V. cable adjustment to provide the shift timing you desire for your driving style without fear of burning up your transmission.

HP7498HD Transbrake Solenoid Tips

HP7498HD TRANSBRAKE SOLENOID TIPS FOR PROPER OPERATION
The Hughes Performance HP7498HD transbrake solenoid is a unique oversize heavy duty solenoid assembly that is rebuildable with our readily available replacement coils and seal kits.  This solenoid is designed specifically for use with our HP6282 and HP7482X Powerglide transbrake valve bodies.  This solenoid is also included as standard equipment on all of our transbrake-equipped Powerglide transmission assemblies.

Caution must be exercised when installing the HP7498HD solenoid into your Powerglide transmission.  This solenoid features a unique length of plunger travel that is generally only compatible with a Hughes Performance HP6282 or HP7482X Powerglide transbrake valve body.  Use of the HP7498HD solenoid with a different brand of Powerglide transbrake valve body may result in the incorrect function of your transbrake and could potentially lead to damage in your Powerglide transmission.  Hughes Performance only recommends the use of the HP7498HD solenoid with a Hughes Performance HP6282 or HP7482X transbrake valve body.

What is Torque Converter Stall


Torque converter stall speed is the maximum amount of engine RPM that can be achieved in an automatic transmission-equipped vehicle while the transmission is in a forward operating range without generating any driveshaft motion.

All advertised stall speed ratings of all torque converters are nominal ratings regardless of the manufacturer or converter design. These advertised ratings are not indicative of the actual stall characteristics of a torque converter. Advertised stall speed ratings are published simply as a general guideline to help in the selection of the correct torque converter for a customer’s application. A torque converter will provide a range of stall speeds based on the amount of load that is placed on the torque converter. Many factors influence torque converter stall speed including; output torque of the engine, vehicle weight, rear axle ratio, rear tire height, torque converter diameter, impeller fin angle design, stator design, impeller-to-turbine clearance, stator-to-impeller clearance, stator-to-turbine clearance, and brake bias.

The GM95B And GM96B
Hughes Performance has released the new Pro-V and Pro-VI series billet GM95B and GM96B torque converters.  These latest generation custom built torque converters include a CNC-machined billet steel 1-piece front cover, and are the strongest and most efficient 9.5” torque converters currently available in the performance aftermarket.  The billet cover offers significant strength and durability increases over our original stamped steel welded-ring design.  This upgrade strengthens the entire converter assembly, virtually eliminating the possibility of ballooning as well as mounting ring failures. The new GM95 and GM96 billet torque converters are readily available for all Powerglide, TH350, and TH400 transmission applications.  All older design GM95 and GM96 torque converters can also be upgraded with our new billet cover.
