4 speed auto tranny
I Was Wondering, I Have Been Reading A Lot Of Comments About Transmissions. I Recently Put A High Performance T350 Tranny In My 79 Vette, But I Need A 4th Gear. Is There A Direct Bolt On Solution? I Was Told A 90's Iroc 4 Speed Would Work. Can Anyone Give Me A Suggestion? I Have 500 Plus Hp In My 383 Stroker, But Ater About 90mph, The Rpm's Are So High, I Gotta Back Off. Someone Also Said To Change My Rearend Gears. Whats The Solution, Thanks

that's exactly what I did. You'll need their TV Made Easy kit, Install kit, Shifter conversion kit and do yourself a favor and get their xmember. No need to worry about the stock drive shaft as it fits just fine. Call BTO and let them know your tire size so that they'll install the correct speedo gears for your. About forgot that you'll probably need an aux tranny cooler.
