how does it shift otherwise???
i know you said shifts good....but what rpm's for part throttle shifts? wot shifts? etc

if you are doing 30 mph in fourth gear does it double downshift?
if not you have a problem

TCI did that so the trans wouldn't keep shifting from 4 to 3 under a load. If you want 3rd you have to manually go there.

TV Plunger & Sleeve for 700R4
Replaces stock assembly to prevent part-throttle downshifts from fourth to third gear from occurring until approximately 85% throttle has been applied whereas most OEM setups will force a part-throttle downshift around 50% throttle opening. You can also restore proper downshift performance by replacing a worn, stock assembly with this kit.

tci already fixed this problem!!!!!
