Hey, first off its auto tranny. I dont believe its my actual tranny causing this "lag" but here it is. I go it shifts to 2nd or 3rd or whatever, and then when i floor it, sometimes, not always, takes like 1-2 secs to downshift while i have my foot to the floor. This doesnt always happan but sometimes it does and its annoying. The actual gear changes are all fine and smooth tho. Everything else is fine with the tranny, its just the actual time to downshift, sometimes, is a lot longer then usual. I dont think its my tranny.. nothing else is problem, and a lot of the time there no problem. Could a bad KS be causing this? Thanks in advance for any help

its a slushbox, what did you expect?

 

Same happens to me, but I'm selling my car in the spring so I don't care. Just upgrade your torque converter and vb and you should be fine

 

My tranny used to do that -- especially with the A/C running. I installed a grounding kit and that helped to eliminate the lag, but I suspect that the change was more a result of the ECU being reset due to the battery being disconnected for nearly an hour.

You can do likewise. I believe there are some instructions in a sticky on directly resetting the ECU, or you can simply disconnect the negative battery terminal and leave it disconnected for at least 30 minutes.

You can also try installing a grounding kit (you can get one on eBay for less than $10...or make your own) and getting your fuel injectors cleaned.

The fact that it happens more frequently with the AC going rules out any problems with the tranny itself. The electronics in your car (ECU & PCM) are what actually determine when to shift based on a number of factors, with engine load being one of them. Since the AC puts a greater load on the engine, shifting should occur sooner rather than later.

Let's face it -- computers can be very stupid at times, and the ones in our cars are no exceptions.

That is why simply resetting the control modules may correct the problem.

 

What did you use for you grounding kit, did you buy it off ebay, or did you make your own, or buy it matt bhelm

 

I bought one off of eBay for $9 + shipping. However, it came with zero instructions...so I turned to the Internet to find them. What's interesting is that there are a number of variations in how to hook them up. I followed tghe daisy-chain approach.
