Rickm6 Posted July 9, 2005 Report Share Posted July 9, 2005 My 99 STS with 45K miles doesn't seem to be upshifting as many times as it should. I count 4 upshifts total from a dead stop. Shouldn't I have 5? That would include the torque converter lockup right? When I'm in "D" I can down shift to third so I know all my gears are there, but shouldn't I notice the RPM's go down when the converter locks up? Car doesn't seem to downshift as quickly as it used to. In other words when I make a fairly significant throttle change this car would downshift and go RIGHT NOW. Now it simply accelerates off without downshifting, much less fun. Any thoughts? TIA Link to comment Share on other sites More sharing options...
JimD Posted July 9, 2005 Report Share Posted July 9, 2005 First to second is one shift. Second to third is two. Third to fourth (OD) is three. And lockup (if you can feel it) is four. Jim Drive your car. Use your cell phone. CHOOSE ONE ! Link to comment Share on other sites More sharing options...
Rickm6 Posted July 10, 2005 Author Report Share Posted July 10, 2005 Jim, Your explanation is better than mine, either way, I'm not getting any lockup. Even if I can't feel it, you could see it on the tach. Anyone have any idea why? Is it a sensor? Link to comment Share on other sites More sharing options...
adallak Posted July 10, 2005 Report Share Posted July 10, 2005 Jim, Your explanation is better than mine, either way, I'm not getting any lockup. Even if I can't feel it, you could see it on the tach. Anyone have any idea why? Is it a sensor? While driving with constant speed (50-60) and gas pedal depressed, with (your) left foot slightly tap the brake pedal to activate the brake switch and unlock the converter. If you see 100-200 RPM increase your converter lock-up is working properly. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
Ranger Posted July 10, 2005 Report Share Posted July 10, 2005 Could be a TCC solenoid but that should set DTC. Maybe a bad or mis adjusted switch on the brake pedal. Search the archives for TCC or VCC. Lots of info on it. Link to comment Share on other sites More sharing options...
Rickm6 Posted July 10, 2005 Author Report Share Posted July 10, 2005 Great ideas guys, I'll check them out. No codes show up and I'm certain its not the air kicking on. Let me ask everyone this, I have a Mitsubishi Diamonte that "learns" driving habits and adjusts shift points to the driver. Is there a chance in hell that this thing thinks I'm looking for gas mileage and has decided to shift like an old lady? The thing drives like the "Cadillac" that everyone thinks it is. I can't stand this any longer. Link to comment Share on other sites More sharing options...

Rickm6 Posted July 10, 2005 Author Report Share Posted July 10, 2005 adallak, Thanks for the reply, then there is certainly something wrong. Sucks to be me. LOL Link to comment Share on other sites More sharing options...
Rickm6 Posted July 10, 2005 Author Report Share Posted July 10, 2005 Although I will check the constant speed, tap the brake pedal at the same time trick. Thanks. Link to comment Share on other sites More sharing options...
Rickm6 Posted July 11, 2005 Author Report Share Posted July 11, 2005 Okay guys, converter lockup IS working, but still is slow to downshift. At times I have a bit of a shake at idle, could it be that the thing is missing a bit? Would a small miss on one cylinder cause the car to be slow to downshift? I pulled the front spark plugs and the number 6 plug was wet with gasoline, whats up with that? Leaky fuel injector? Would that cause a miss? Thanks again.

adallak Posted July 11, 2005 Report Share Posted July 11, 2005 This one may be unrelated, but have you done fuel rail recall? The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
Ranger Posted July 11, 2005 Report Share Posted July 11, 2005 Yeah, sounds like a leaky injector. If it was "wet" then maybe the cylinder is not firing at all. There's your mis. I wouldn't think that would affect shifts though. Link to comment Share on other sites More sharing options...
Rickm6 Posted July 13, 2005 Author Report Share Posted July 13, 2005 Thanks guys, I'll check out the injectors. Whats up with the fuel rail recall? I'm not familiar with that. Link to comment Share on other sites More sharing options...
adallak Posted July 13, 2005 Report Share Posted July 13, 2005 Thanks guys, I'll check out the injectors. Whats up with the fuel rail recall? I'm not familiar with that. Several members had to replace plug wires right after fuel line recall. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
Rickm6 Posted July 13, 2005 Author Report Share Posted July 13, 2005 Fuel line recall? How much of the fuel line do they replace? Is it hard line or hose? Thanks. Link to comment Share on other sites More sharing options...
Ranger Posted July 13, 2005 Report Share Posted July 13, 2005 Fuel rail recall was (is) for '95 - '97. Link to comment Share on other sites More sharing options...
