What does L stand for in a transmission?
low gear
L stands for low gear. When your car is in drive, or D, the automatic transmission will shift through the gears as your speed increases. When your car is in low, or L, the transmission won’t shift. Instead, it remains in a low gear, and less fuel is injected into the engine.
What does 2 and l mean on a gear shift?
2 usually means the transmission is instructed to stay in second or first gear at all times unless a higher gear is required to prevent the engine going over its redline speed. If you have an L and a 2 next to each other, it’s very likely L stands for first gear.
Do you need two gears for a Chevy Trans.?
Two gears, that’s the problem. This trans. can only be run in cars that have a very high hp to weight ratio. It would be fair to say a vehicle weighing approx. 3400 lbs would require an engine output of 1000 hp or more to make it a rational choice, and even then, you would still need a decent final gear to get things moving off the line.
What kind of designator does a GM transmission use?
Most early electronic transmissions use the “-E” designator to differentiate them from their non-electronic cousins, but this has been dropped on transmissions with no mechanical version like the new GM 6L80 transmission .

What’s the rear gear ratio on a Chevy truck?
The stock 60 1/2 ton rear has a perfectly round cover plate and also a carrier or “pumpkin” that can be unbolted from the front of the axle housing.

What’s the ratio of first to second gear?
Very wide first to second gear spread. First gear is a 3.06 ratio Second is a 1.62 ratio. This nearly equates to skipping from first to third gear with a manual trans. This kills acceleration when these trans go into second gear on a carbureted engine with a healthy cam and large runner intake manifold. Compare this to a TH350.
What’s the lowest first gear on a Chevy?
The 3.06 first gear is so low that any final gear of above 3.55 or numerically higher will have you right at the max rpm at around 35 mph, only to then have your car fall on its face when it hits second gear, feeling like it skipped a gear.
