What causes no transmission fluid in a 4L60E?
What causes no transmission fluid in a 4L60E?
4L60E No Movement in Any Gear The most likely cause of this is either a total pump failure or a complete loss of fluid. This could be due to a significant leak, so if the car has been stationary for a while you may be able to see a puddle of transmission fluid underneath it.
What’s the gear ratio on a GM 4L60E?
The 4L60E is a 4-speed (meaning it has 4 gears) transmission, with gear ratios of 3.06; 1.63; 1:1; 0.70 ( overdrive ). Reverse has a gear ratio of 2.29. It weighs 146 lbs before transmission fluid is added and 162 lbs with it. GM claims that the factory transmission fluid should last the entire working life of the product.
What does electronic shifting control on GM 4L60E mean?
This means that a series of valve pressures made the transmission shift gears. GM made the jump to electronic shifting control with the 4L60E ( E lectronic shifting control). Keep on scrolling down to read more about electronic shifting and its many advantages.
What causes the torque converter to lock in gear?
When the TCC solenoid receives a signal from the engine control module (ECM), it opens a passage in the valve body and hydraulic fluid applies the TCC. When the ECM signal stops, the solenoid closes the valve and pressure is vented, causing the TCC to disengage. This lets the torque converter lock in “gear” or unlock out of “gear.”
Is there a problem with the 4L60E transmission?
Just like any other transmission, 4L60E can also experience problems and might require an upgrade. For better performance, get automatic transmission rebuild kits. Here are 3 symptoms of a failing 4L60E transmission and how to diagnose the problems: No Third Gear – You put the vehicle in drive, start off the transmission, and shift to second gear.
How much fluid does a GM 4L60E need?
The 4L60E transmission weighs 146 pounds dry, and 162 wet. It requires 8.4 quarts (9.64″ torque converter) or 11.4 quarts (11.81″ torque converter) of transmission fluid, Below is a list of common transmission problems with the GM 4L60E Transmission and possible solutions to repair.
Can a 4L60E shift from first gear to second gear?
It is pretty easy to diagnose. The vehicle will shift from 1’st gear to second gear with absolutely no issue whatsoever, but than it acts like it has shifted to neutral. The engine is usually under a pretty heavy load at the time, so it’ll tend to redline before you realize what happened.
Where does the E come from in the 4L60E?
The short answer would be that the shift solenoids found within the 4L60E transmission receive instructions from the ECU/TCM to open and close. This is where the “E” in 4L60E comes from. It means electronic control.
When did the GM 4L60 E transmission come out?
The 4L60-E is the “E”lectronically shift controlled version of the 4L60. The Late 4L60-E was released in 1997 in and fully phased into wide use through GM by 1998 in both RWD car platforms (including the C6 Corvette) and trucks in both 2wd and 4wd configurations.
What causes a check engine light on a 4L60E?
Heavy Shift Into 2nd With 4L60E This could be due to a worn TCC regulator valve. You will also probably have a check engine light on on the dashboard and a diagnostic code of 1870 – internal slippage. The transmission will need to be taken apart to access the TCC regulator valve.
What’s the problem with my GM 4L60E transmission?
For a complete diagnosis on your GM 4L60E Transmission problem, contact us for a Free Diagnostic. 1. Slow, slipping or no reverse: “lo-reverse” clutches are worn out, fluid leak in the reverse apply circuit, or broken sunshell.
Why does my 4L60E have no reverse?
Slow, slipping or no reverse: “lo-reverse” clutches are worn out, fluid leak in the reverse apply circuit, or broken sunshell.
What to do if you have a fluid leak in your transmission?
“lo-reverse” clutches are worn out, fluid leak in the reverse apply circuit, or broken sunshell. It is possible to remedy a fluid problem by removing the checkball from its cage in the case in the rear of the transmission may help (must remove valve body), or adding a high-viscosity additive or other seal restorer product.
