my transmission whineswhen cold, l must rev my engine to get it to catch gears and pull off. can any one please give me an sullution?

It is low on fluid, why not take it in for a trans flush and new filter before you blow it up.

It definitely sounds like it is a few quarts low. Check the fluid level with the engine running, warmed up and on a level surface. Top if off and see if the problem goes away. If it does not l doubt a dirty filter is the culprit. You're beyond a flush and fill, you need a front pump i.e a rebuild. Also, if you do a flush and fill make sure the shop flushes the torque converter and cooling lines as well.
