So during our "winter" when it gets "cold" at night(65 or less) my torque converter does not lock until a while after driving. Like 15 or so minutes, even with letting the car warm up to normal temp. Is this normal?

 

Might sound like some royal purple advice but when my tranny was slipping, like out of every turn and every downshift, and I thought I might need a new one I tried Zmax tranny additive and no lie it stopped slipping after 20 miles or so. Maybe it fixed itself but I think it had a little something to do with it

 

Hmm. I might have to give that a try. Hopefully others can chime in.

Edit: all other gears are fine. It just doesn't lock in when I get up to speed

 

Can you buy that zmax stuff at any auto parts store?

 

Probably a faulty solenoid.

 

If it is your actual torque converter then it wont much help but as far as tranny slippage that stuff worked like magic and I have no idea why. It was slipping bad, put it in as a WTH and it stopped slipping

 

its normal

when the fluid is colder (this goes with any oil) it thickens and becomes harder to move. not to metion the TCC has a lot of parameters to meet before it engages. vehicle speed, engine RPM, trans temp, and throttle position all need to be perfect before it engages. remember the gauge on your dash is for the engine not the trans. your engine could be nice and toasty but the trans may not be at the proper temp to turn that clutch on

 

I personally support Zmax. If you find some just put a drop on some metal and watch it seep in. Crazy mystery substance lol. I generally dont support additives of any kind but Zmax worked wonders on my tranny

 

Okay. I just wanted to make sure it was normal. I guess it's a good thing how cool our trannys stay. Especially our 110+ degree summers and 200+ degree engine bays lol
