4T80E Trans Shift Improvement device


Recommended Posts

So... has anyone tried this: Granatelli Transmission Tuner for All GM 4T80E

Do a web search for their part number 420106

About $120-$125

I don't know about y'all, but my 98 Aurora could stand to have this

Bonus checks come out next week, may give it a try B)
