Gear ratiosĪnother big difference between these transmissions that is important to think about if you are going to swap them, is the gear ratios. Just with these numbers, you can probably calculate that there is a big difference in size and weight between these transmissions. The 4L60E has a weight of 150 lbs without fluid and a length of 23.5″, while the 4L80e has a weight of 236 lbs and a length of 26.4″. The 4L80e is much larger and heavier than the 4L60E. The size & weightĪ big difference is the size & the weight between the 4L60E and the 4L80e transmission. Remember that these are the main differences and you can find other small differences if you carry out more in-depth research. Here are some more differences between these transmissions. There are also different gear ratios and the 4L80E can handle much more torque. The most significant difference between the 4L60E vs 4L80E transmission is the weight & size.

Noise, vibration and harshness (NVH) minimized with gear layout to best control stress levels.Superior shift-ability through use of multi-cone synchronizers and hybrid synchronizer rings made of sintered bronze and carbon.Gaskets at all flanges simplifies installation and eliminates fluid leaks. Increased case strength with three-piece aluminum housing provides outstanding structural stiffness (includes main case, intermediate plate and rear extension).Compact, end-loaded design provides clearance in most transmission tunnels without floor modifications. Designed for multiple applications with three shifter locations.It is available in multiple gear ratio configurations (See chart below). of torque capacity and is capable of engines speeds of 8,000 RPMs with shifts at 7,500 RPMs.
TKX 5-Speed Manual Transmission Features and Benefits Designed to fit classic muscle cars and customs, the TKX has a tighter, more streamlined case. This brand new design is made from the ground up as a strictly aftermarket transmission. TREMEC has normally sourced their aftermarket transmissions from the OE side, such as the Magnum T-56 and the T-5. The New TREMEC TKX is the new 5-speed in town.
