The transgo would probably make the normal shifts like your current ones with the perf shift, and perf shift would be an additional kick with it.
Today my friend brought his new to him 2002 kia sportage to check it out. Not my taste in a car but he got it for a good deal, it was shipped from canada since his cousin was selling it. $3300 total after canada and mi taxes, and cost of the vehicle and it has 76k miles. Not too bad really. It has some rust on the body, and every bolt is rusted tight on the thing.
His headlights stopped working recently, later found out they were just really dim but in the sunlight we couldn't tell. Fuses were good, checked the bulbs reluctantly since when do both go at the same time? They were good and checked for voltage at the connector and got 12v..weird, but saw the connector was corroded. Checked the other side and it was the exact same thing, but that one got really hot and melted the connector. Weird both connectors were corroded and caused both lights to go out at the same time. Bought 2 new connectors and soldered them in, used plenty of dielectric grease on the contacts, and they're good as new.
