Review on 🏎️ J.W. Performance Transmissions 92451 Ultra-Bell: Superior Solution for TH400 Transmissions by Javarie Malick

This clock tower is definitely a stronger upgrade and has an SFI rating. It took a bit of effort to cut off the stock Th400 bell, but not too hard. The instructions could have been better. I ran into a problem with the flexplate gap. I had a 14" 168 tooth flex plate and couldn't delete the UltraBell. I had to upgrade to a 12.8" 153 tooth flex plate, which also meant buying a new starter motor. This installation issue was not mentioned in the instructions or description. In the end, when it was finally installed, it was a good part of the added security and durability to my Camaro.
