When the throttle is opened, cable movement and tension increase, modulating line pressure accordingly via the throttle valve, which is what you want when power is applied. Giving the Transmission a better mechanical advantage and in turn, better take-off acceleration, slightly lower fuel consumption, and designed for better gearset strength. If it is overfull, you must siphon out excess fluid or face foaming and damage. Front Pump Assembly Installation Step1: Install Front Pump Thrust Washer The nylon thrust washer sets up clearance between the pump and reverse clutch assembly. Then check the throttle valve pressure again with the thickness gauge or drill bit. With the engine at idle against the throttle stop, insert a thickness gauge or drill bit.
Then again, we believe the Easter Bunny story, too. Again, everything must have generous amounts of lubrication. Keep in mind these adapter kits alter the transmission mount location by 1 to 2 inches toward the rear of the vehicle. Step 13: Install Forward Clutch Piston Return Springs Use a C-clip retainer with the clutch piston return spring. What it did have going for it, however, was an overdrive unit and a brand-new aluminum case, shaving quite a bit of weight off the transmission. Besides utter reliability for most street and race applications, this also means that there will be no more hunting for gears in slow-moving traffic: Pick a gear, and it stays there.
If start-up is uneventful you are good to continue. Measure the clearances between the pressure plate and the first disc. The cam pushes the parking pawl into the rear gear, locking the output shaft. Planet gears should feel solid with no wobble, indicating acceptable inside gear and bushing wear. Unfortunately, this turn of events occurred at the 2-3 upshift, which caused clutch and band slippage, along with destructive heat. LenTech addresses this issue with a non-locking overdrive, which means the engine stays on the torque multiplication side of the converter for better acceleration even in third gear.
The Dominator Junior transmission comes with the 14 performance torque converter with your choice of 1800, 2500 or 2800 stall speeds. Fluid under pressure flows first through the outer hollow input shaft during torque multiplication acceleration and light throttle and into the geartrain in ranges 1-2-3 and reverse. The throttle valve pressure port gives you throttled line pressure, which corresponds with throttle position. Cam Type What type of cam are you running in your motor? While these modifications can be done to 4R75W transmission, the results are not as dramatic as some of the details of the J-Mod bigger holes in the separator plate and gasket were done to the transmission in its design. You should use 1967-up because of the shift detent positions. These clutches lock the reverse clutch drum.
Step 5: Secure Governor with Snap Ring The snap ring keeps the governor in place on the output shaft. If you have the budget, the aftermarket has your 4R70W performance parts. A trusted machine shop can cut a new groove for the snap ring that allows you to add clutch friction and steel plates. Hard parts such as the planet carrier should be closely inspected for unusual wear. The ring gear has already been fitted.
Performance Automatic combined high performance racing clutches and high performance lined bands to improve heat dissipation at the application points. Make sure the parking brake is set and the selector is in park. Step 2: Install New Bushings and Seals Install a new bushing and seal in the tailshaft housing. This is 40 to 60% more than stock. Step 2: Rebuild Governor Disassemble, clean, and inspect the governor, which is mounted on the output shaft.
Extra clutches are added to the direct clutch drum Alto Red Eagle Power Pack. Are you running nitrous, a turbocharger or supercharger? It should turn freely in one direction and lock up in the other. And when crisis repeated itself later that decade, Detroit was ready. Step 9: Install Front Pump Seal Use plenty of transmission assembly lube to install the pump perimeter seal. On the left is the 157-tooth version for the C4 Cruise-O-Matic with a 28-ounce offset balance. However, some items must be made to order and take a bit longer for you to receive. Step 16: Check Forward Clutch Clearances Load the pressure plate after all frictions and steels are in.
When it shifts from 1st to 2nd its got a really smooth shift and it puts a smile on your face. Step 12: Install Forward Clutch Piston Special Tool Use the seal protection tool to install the clutch piston so the seals glide in smoothly. Then turn the adjustment screw three additional turns clockwise. Add torque converter upgrade if needed. Each steel plate should be measured with calipers prior to installation.
