I thought I'd posted this before but I guess not...

Yes, as far as I can tell you can make it work but you'll need an upgraded transmission (and possibly engine) ECU as well as a TL Helms manual to figure out how to wire it all out. It wasn't worth it to me...I guesstimated it would have cost at least $400, not including my time.

The 99 TL shifter is the only one that has the correct 4 speed shift gate, FYI.
