Auto to manual conversion

If you decide to keep your car as an auto; and still want to have fun;
Get yourself a lock up trans, a semi-auto shift kit, at least a 2800TC...... with at least 3.55s with a SureGrip. This combo acts like a 5-speed manual. Well more like a 4.5 anyway.
If you find a wide-ratio A999 then you can use the next smaller rear gear.
if you don't care about hiway rpm, then use your A904 with 3.73s or better.
Imo, for this combo, the standard A904 has tighter shift splits and especially the 1-2. But with a 2800TC, the A999 ratios are not that bad. The lock-up is only a half-gear.
If yur having trouble imaging this, just ask.
