I have a 8 inch 5800rpm spragless Transmission Specialities converter behind my BBC.
I have run this converter for the last 2 seasons and was pleased with it's performance, thats is... till I found it has over 17% slippage :shock:
I'm pretty sure it was loose from the get go and they do offer one free tweak within the first 6 months. I just never knew it was loose till someone on here ran the numbers for me.
I wouldn't be afraid to buy another one though.
