Can you use a 4L60E without a computer?
Externally, all it needs is a 12-volt source and an engine-vacuum reference. However, if your trans is, in fact, a 4L60E, running it off a computer is mandatory. Never mind TCC lockup; without a computer, the trans won’t shift at all.
Does a 4L80E need a computer?
A 4L80E can be made to run without any electronics but it has to be full manual valve body which would get old on a daily driver. Never mind TCC lockup; without a computer, the trans won’t shift at all. …
Can you manually shift a 4l80?
However, the 4L80E can be easily converted to a manually shifted valvebody, which eliminates the need for the computer and much of the electronics and wiring. This conversion turns the 4L80E into a great heavy-duty analog overdrive transmission that can be easily swapped into almost any high-horsepower 4×4.
How much HP will a 4L80E handle?
How much power can the 4L80E handle? A totally stock unit or rebuild will typically live well with up to 450 flywheel HP/TQ.
What makes a 4L60E Shift?
The 4L60, along with many transmissions of its generation, was controlled by a hydraulic system. This means that a series of valve pressures made the transmission shift gears. GM made the jump to electronic shifting control with the 4L60E (Electronic shifting control).
Is there a non electronic 4l80?
The only way to make a 4L80E shift without the electronics is to install a manual valve body. It requires the electronic control to operate the shifts on its own. You could install a manual valve body, put it in drive, and go, but you’ll only have one gear and it would be drive.
Can a transmission be changed on an E4OD?
Transmissions without the gear can have the output shaft changed, but complete transmission disassembly is required since the output shaft is in the back and the transmission disassembles from the front. E4OD transmissions manufactured prior to 1995 had an issue with the MLPS, or “Range Sensor”.
Do you need an adaptor for an AOD transmission?
If you’re going from a C4 to an AOD with a small-block V-8 application, it is important to understand the differences between them. If you’re going from a C6 to an AOD in a big-block application, the differences are even more significant because you’re going to need an adaptor kit.
Why does my AOD feel like it is shifting?
It Just causes thumps, bumps and extra wear. Set the TV so that the shifts are smooth and not late. BLOCK TYPE-TV CABLE ADJUSTMENT IMPORTANT: The AOD transmission may feel like it is shifting at the right time when the TV cable is actually way off! The transmission will work for a while and then FAIL!
How does an AOD affect the transmission package?
An AOD behind an FE or 385 makes the transmission package 1 to 2 inches longer because you’re adding 1 to 2 inches to the bellhousing through the thickness of the adapters.
