Yes I know, I'll try to do the swap as soon as possible, believe me. But the situation is this; when I run my car after 3 or 5 min of start the engine, (maybe a lil' bit cold), It runs just on 1st gear, no shifts till the car warms up completely. Then It shifts fine. But when it have to shift from 2nd to 3rd, seems like sleeps then grips when I release the gas pedal. Everybody says something different about that. Ex: the wire that goes from the throttle to the tranny might be adjusted, others says It's the shift solenoid or the TCU...but, what's really happenning?, please help thanks.

could be shift solenoid..and tcu as tranmission control unit ?? or am i missing a letter or something -
Those are all possibilities in my mind, except the transmission throttle cable. Which as far as I know that cable just controls throttle B pressure which determines how much lock up you get when the lock up clutch solenoids turn on.
You can test the solenoid by measuring the resistance between each terminal and ground (spec: 12-24 ohms) and if within spec apply battery power to each terminal and you should hear a click, if you don't it needs to be replaced. As far as the TCU possibility you can replace it with a known good one to see if that is the problem.
About the missing letter, it needs an s after the first n in transmission.Comment

does the temp could affect the solenoid work? what else could be affected by the temperature in a transmission? I forgot to mention, sometimes (not always) the "S" light on the cluster blinks after few min. running too. So, I'll check the codes tomorrow. but please help me on that.Comment

I believe it's your TCU. I had a similar problem. Try shifting it yourself to see if it works fine. If it does, the computer(TCU)is not working correctly.Comment

You can check the transmission codes the same way as the ECU codes, short the short connector and the D4 light should flash when you turn the ignition on to position 2. If you had mentioned you had codes we would have told you to just check those first. Have you checked the transmission fluid?Comment

yes, the T/f is good, even I put a treatment for It, feels 10% better but the shifting problem persist. [/I]Originally posted by rcpaul View PostComment

This morning I drove all the way to my job on "s" mode. shifts normal but If the car is suposed to be on 2nd, and the knob is on d3, that makes the slip problem when it have to shift, I have to release the gas pedal to get 3rd. No blinking on the "S" but i'm worried about to provoque more damage to the tranny driving it like a manual.Originally posted by cleanwithit0607 View PostLast edited by F22BPR; 04-10-2010, 01:39 AM.Comment
