The 4L60 transmission was the primary transmission part of plenty of General Motors rear-wheel drive vehicles for almost two decades since the release. Over time, the manufacturers released several other modifications that worked different in various cars. Even a first-time car buyer understands that one sees in performance is simply a printout of the mechanics. The most common questions for novice mechanics’ fanatics is whether all 4L60 releases are the same.
Are there differences between the 4L60 transmissions?
You cannot afford to use any of the series’ transmissions, because assuming they all have similar operations will cause extensive complications. General Motors, between 1990 and 1992, released the 460. It had a specific design to fir in rear-drive high performing vehicles. The first version was known as 700R4, which then became 4L60 in the middle of the manufacturing cycle.
4L60 was common in Corvettes, Pontiac Firebird, and Chevrolet Camaro. General Motors later released 4L60 as the third of the transmission’s trilogy. It is important to note that all versions are still present in the market, but they maintain fundamentally different purposes. Gearstar stocks variations of all three transmissions.
The 4L60 transmission has a case connector on the wiring harness close to the passenger side. The 700R4 does not have a governor case. The engine supports a 6000-pound Gross Vehicle Weight Rating, which is lesser than the supportive capability of the 4L60E, which supports a GVWR of 8600 pounds.
One of the most outstanding differences between 4L60 and 4L60E are the mechanisms of control. The latter version is controllable using a computer while the previous one typically uses a TV cable. These two transmissions cannot complement one another’s role. The replacement of the 4L60 with 4L60E began in 1996 and continued to 1998.
The 4L60 transmission is still present in lightweight applications. The popularity of the 4L60 technology revolves around the following mechanical aspects:
- Low-speed performance
- Performance of the fuel economy
- Electronic control
The definite values of each transmission determine how they will fit into the car.
Which one should you use?
Replacing one with the other will exhibit problems with timing when to shift or kick down. The transmission will also have wrong calibrations for the vehicle’s designated speed. These two transmissions have vastly different geometries; hence, they will not engage the torque convertors in similar ways. Additionally, our store has 4L60 transmissions of levels 2,3 and 4.
Level two has a 450 horsepower and supports 425 pounds of torque. Level three has a 500 horsepower and a torque convertor of 500, whereas level four has a horsepower of 600 and torque convertor of 600 pounds. You can call the office for prices of additional services such as the addition of specific cooler fans, drain plugs and fill tubes and sticks.
The Gearstar technicians would have to use adapters and other specialized tools to ensure the smooth continuation of the operation. Engage one of our lines for professional assistance on which 4l60 transmissions suits your vehicle’s setup.
