Do u feel a FLT level 5 can deal w/ a Radix(if I go that route?) What's the worst thing about the conversion? Not tryin to threadjack, if needbe, feel free to PM.

Yes my 60' time is the same and more consistent. Yes its about 100lbs heavier. I bought the best 65e FLT has to offer it didnt last 5k miles behind my Radix. Installing the 80e wasnt bad at all. The 65e looks more like a foreign trans then like a truck trans

Do you know anyone with a 6.0L pickup you can take for a spin? The shifts in a 4L80-E feel different compared to a 700R4. The ratios are closer too, so less RPM drop even with a stock low-stall speed converter.
It's definately an investment. You can expect a 5% hit (or more) to fuel economy with the extra weight, frictional losses, and lesser overdrive. Such is the price of boost...
