One way each of these can be made possible is through simple 4L60E performance transmission upgrades.
Now, the automatic transmission has come a long way because, for almost 40 years, car manufacturers have had their fair share of hassle while trying to design the best fuel economy engine.

Their attempts are evident in the use of a computer-operated carburetors and even an electronic throttle body fuel injection in a bid to slow down fuel consumption. General Motors, for instance, devised the Turbo-Hydramatic R4 overdrive automatic transmission in as an upgrade to the TH three-speed automatic. The R4 was quite unique in comparison with previous models which were designed by the company.
This is because its shift modulation was carried out with the use of a device known as the throttle valve TV cable. While the TV cable was able to modulate shift programming using throttle position and vehicle speed, it was still unable to bring about a perfect balance between fuel economy, driveability, and longevity. Another problem that was posed, is irregularities in the line pressure and timing when a car owner improperly adjusts the TV cable.
The latter could potentially lead to the R4 transmission being burnt. This led to the development of 4L60E, a computer-controlled transmission that is still based on the R4. Today, you can find the 4L60E transmissions in GM vehicles such as:.4L60E Design Changes and Tags
There are several 4L60E mods you can count on as a performance enthusiast, but no matter how tempting it may be to do it yourself, you need to ensure that you are a transmission builder who has garnered a lot of experience. Accordingly, highlighted below are some of performance upgrades for greater torque capacity which you can try out.
Keep in mind that the goal is to increase the torque capacity to handle horsepower. The 4L60E mods we have outlined above can ensure that whether you are a builder or a car fanatic with some level of experience, you can increase the horsepower and torque capacity of your car.
The result can be quite rewarding starting from a higher level of performance, and reduction in fuel consumption. If you want a more speedy ride, then these 4L60E transmission mods will surely suffice. GearStar Performance Transmission N. No Comments. As a rule, always lay out the high-performance parts on an assembly bench in order to ensure that you do not miss out on the parts that are in dire need of enhancement.
You can then proceed to thoroughly clean, inspect, and paint the transmission core. Rebuild with an improved, thicker sun shell. On the other hand, 4L60E builds carried out with a thicker sun shell that is stronger can prevent failure.
It will also enable your 4L60E transmission to handle horsepower which is equivalent to a 20 percent increase in torque capacity. Use a larger clutch with an input drum reinforcement sleeve. In this case, you can try out a larger clutch overrun clutch apply piston while also using a reinforcement sleeve. The result is increased stability and hydraulic holding power. Keep in mind that stability and smoothness are also determined by having less friction and as such, consideration has to be given to the Teflon-impregnated stator support bushing.
Stamped Steel forward clutch apply pistons. You have the option of settling for a forward clutch apply pistons that are made of steel or cast piece. When either is compared, one with a stamped steel is the better option because it is less prone to failure while in use.
Use more clutches and larger gear band servo pistons. For a greater band-apply capacity of around 18 percent, use larger gear band servo pistons. A Raybestos ZPak clutch pack, for instance, features materials that reduce friction and as such, help to dissipate heat.

Not valid on auto parts purchased for commercial use.In most automatic transmissions, the torque converter is mated to the pump of the transmission in two places: the input shaft and the stator also called a stator tube or stator support. This splined piece of steel centers the torque converter into the pumpprovides lubrication circuits within the pump, and can also stabilize and support the input shaft in some setups.
In many OEM applications, such as the powerglide and TH, the tube is pressed into the pump casting. In high horsepower and torque setups, the stator in the torque converter is receiving tremendous amounts of pressure from the power generated by the engine.
This heavy load is placed onto the pump's stator tube. If this component fails, it will often turn or twist within the pump casting. A visual inspection of the pump's exterior will not indicate any failure.
However, the function of the transmission and torque converter can be greatly affected. If your transmission and torque converter have suddenly changed their performance profiles, check the stator tube during a full disassembled inspection to make sure this sometimes overlooked component is operating properly.
A spun or broken stator tube can be replaced with an aftermarket version like the one pictured above. Made from chromoly steel, this is a big improvement over the OEM tubes. However, the tube is still pressed into the pump body, which can fail again in some situations. The best solution for a racing car or truck is a completely aftermarket pump like our high volume powerglide pumpwhich features a bolted-in stator support tube. This tube is virtually unbreakable in even the most stressed combinations such as Pro Mod and Monster Truck class racing.
The aftermarket sleeves are held in place using only Loctite, which makes it impossible to determine if the sleeve will stay put or rotate after only minimal use.
Another problem is that metal chips produced during manufacturing become trapped between the sleeve and the stator support shaft. After the shaft is installed and the unit pressurized, the chips flow through the transmission and cause damage.
Sonnax also offers an improved stator support shaft S-1K for and newer 4LE transmissions with mm torque converters that prevents sleeve rotation. The Sonnax replacement stator support shaft includes pressed-in front and rear stator shaft bushings B and A. This part is longer than the early 4LE stator support shaft and cannot be interchanged.

4L60E Transmission Mods That You Can Count On
It provides a good introduction to Norway for the first time visitor and I would highly recommend it. Thank you so much, we had a wonderful trip and Nordic Visitor and in particular Cecilia were wonderful.
You have made it a special and memorable time for us and we thank you for all your work and attention to detail. My wife and I completed the Iceland Full Circle self drive trip on August 26 arranged by Hilmar and Signy of Nordic Visitor. We were happy with all of our accommodations and very glad that we waited until after our trip began to plan a couple optional excursions such as the zodiac boat ride on a glacial lagoon and the Blue Lagoon on a rainy day the day we departed.
The scenery was so spectacular that we hiked more than I expected we would plus since we lucked out on the weather, we wanted to be outside. Bad weather our last two days caused us to explore a textile museum and the Skagafjordur Folk Museum featuring turf buildings.
Helpful hint-if you want to climb Mount Namafjall (mud pots, fumaroles, etc. I would recommend this service to anyone. They made our trip to Sweden effortless. We encountered passport problems at the start of our trip which resulted in a delay and Cecilia was able to rearrange ps4 60fps games for us.
She went above and beyond in service to us. This is the only way to go and I would definitely use this service again. Our Southern Iceland self-driving tour was wonderful.
Working with Larus, at Nordic visitor, was a breeze, even though he was coordinating a trip for members from the US and Australia. He changed accommodations and upgraded things without any problems. The maps and booklets really let us know what to expect and how to prepare. Our accommodations were wonderful. There was a mistake made in rooms, one evening, but Larus found another hotel in a very short time.
We had to drive a little further, but it was well worth it. The last night was right on the busiest street in Reykjavic.
