I was comparing it to the 5-speed. The 5-speed is quicker for a couple of reasons. The ratios, the ability to "dump" the clutch, the control over the shifting and the lack of the torque convertor so there is no slippage. The "improvements" I have done include the P J Grady cooler, the heat-shrink tubing on the shift cable, heavier springs in the clutch packs, and the "mod" to the shift computer. I also have a rebuilt torque convertor with a brass thrust washer instead of the origional plastic one. Most of this only will add to the reliabitity and longevity, the harder springs give me firmer shifts, kind of like a "shift kit". The BIGGEST improvement that can be made is good old-fashioned preventive maintaince. Check the fluid level and condition often and replace it regularly. Do all of the external on-car adjustments. Tell us what improvements you have done.
