I have a 98 Kia Sephia with two trouble codes:
One is P1624 TMC to PCM MIL Request Signal Circuit Fault
Two is P0740 Torque Converter Clutch Circuit Malfunction

Could someone please help me decipher these codes?
Is there is common fault with these codes i.e.
torque converter lock up solinoid shorted out or
could it be more serious? Has anyone else had
similar codes and what turned out to be the problem?
Wiring problem? Or other?--Thanks for any help--Glenbo
