What is an LS transmission adapter?

An LS transmission adapter is a piece of equipment that allows for a quicker and more accurate fitment of an aftermarket transmission to an LS engine. The adapter plate allows for many types of transmission to be fitted to an LS engine, therefore increasing the range of options for transmissions. Enthusiasts often choose to upgrade the transmission for better performance and higher speeds around the track. Engine swaps are popular too, and the modular design of the LS engine makes an LS swap more straightforward than other engines. The LS1, LS3, and LS7 are all high-performance engines designed for corvettes, and they make popular replacements for serious upgrades. A new LS engine does require a transmission swap too for the best boost in performance.

What is the purpose of a transmission swap?

Even if you swap out your current engine for a more powerful one, that doesn’t necessarily translate to more power and speed on the track.

Transmission swaps often accompany engine swaps, but an intelligent transmission swap using a transmission adapter can harness the power of your existing engine in profound and measurable ways.

What transmissions can be coupled with an LS engine?

Fitting an LS transmission does require an LS transmission plate, however, but these are thankfully easy to come by from trusted suppliers.

How much should an LS transmission swap cost?

Part of the reason for the popularity of LS transmission swaps is that the LS range of motors are remarkably well known and a mainstay with hobbyists and enthusiasts. Many swaps involve the use of a transmission adapter as well as the transmission, which should be factored into the price. A DIY transmission swap can cost anything from $1000 to $3000, depending on the transmission and adapter used. For professional installation, and the many variant factors that go into making an estimate from a reputable shop, prices can skyrocket to between $2000 and $9000. As with most modification projects, it makes sense to shop around for an expert who can give you the result you need at the best price. As many shops specialize in this sort of swap, affordable options can be found.
