I did a search on this on test.maxima.org but couldn't find anything.
My AT granny-tranny has been shifting harder than it should ever since I got the car. I mean it's not neck breaking but there is nothing near "luxury feel" to it at all on any shifts. I flushed the tranny, monitored the ATF level constantly and there are no leaks. Since one of the first things to check when the shifts are rough is the TPS adjustment I went ahead and checked that last night.

The factory voltage specs for the range from closed throttle to WOT is
0.5K Ohms - 4.0K Ohms

My TPS checks at
0.59K Ohms - 4.22K Ohms (.1K to .2K higher than recommended)

Does anyone have experience with TPS adjustments? Would this little deviation make a significant difference in throttle position signal sent to ECU and TCM? How hard is it to adjust the TPS?
Any input appreciated.

Those measurements sound just fine, leave the TPS alone.

Check the dropping resistor located on the strut tower next to the factory air box.

Thanks, Tom!
I suppose I should check the dropping resistor resistance... Do you happen to know what the specs for it are?

Sorry my Hanyes manual isn't with me today... Go to the test site and search on Dropping Resistor. I know it's retavely low, like 10 or 15 ohms, something like that.

I would but the search at the test site is not working as it should (http://test.maxima.org/showthread.php?t=235853). I don;t remember seing it in Haynes but if it is there I'll find it when I get home.
Thanks.
