I replaced the seals in my transmission but still had leaks & now it won't go into reverse. It will go in all other gears but revearse. Now what?

Have a professional look at it. Transmissions are not something that the average person can fix.

. Check the alignment and operation of the Transmission Range Sensor (TRS)--replace, if necessary.

. Check all under dash and under hood fuses with a test light or multimeter.
