There are plenty of posts about quickshifters on tlr and tls, but most are a few years old now and tech may have moved on a bit. I recently fitted a dyno-jet up only quickshifter on my 99 tlr and its fantastic. I went with dyno-jet because I was always going to fit a PC5 ( for mapping, I dont want to re-flash the ecu) and this has the facility for a quickshifter. You will need a modified shift rod and then time on a dyno to set it up/ enable it, but if you get the model specific pc5 and quickshifter, its plug and play. Easy to fit and easy to disconnect ( although you won't 😉). Let us know how you get on 👍
