Thank you guys' warm reply. I still use the old TSS. Should I replace the it with the new one? I didn't consider TSS as a cause at the beginning. I thought a bad TSS can cause 1-2 bang shift but my shift is really smooth up to now. I only have bang shift after freeway driving.
Hi, unisys12, thank you for your long reply. I measure the solenoid pack. The resistance between 3-4 is 13.6 ohm, sounds normal. I didn't do the short to ground test. I will do it tomorrow. I did the road test as you recomended. It seems that the converter never locked-up. When I maitain a speed of 50M and then press the brake, nothing happen. The rpm doesn't increase at all. What's that mean? Sounds this is a clue to my problem.
