Ok with my c-4, I'll be driving and sometimes it stays in second gear longer than normal then it kicks into third after getting up to around 40-45mph. Usually it does it around 30-33mph when just driving normal.

A certain band is o.k. for cold/warm conditions, sounds like low fluid level. Check in warm condition, running shift lever through gears, then take a multiple sampling of the dipstick level indication. Otherwise bands might be worn.

IF the Band and fluid check out, it could be caused by a dirty filter, a bad modulator valve or possibly a Sticky valve inside the valve body. I would check these out in this
order. If the fluid is low and there are no appearant leaks, I would still check the modulator because a hole in the diaphragm can cause fluid to be sucked into the intake. Hope this is helpful

the modulator valve will hold the gears longer when low or no vacuum is present also.., but it would also hold first gear longer..
