the car is a
1995 altima GXE, 143,xxx on clock, runs and drives just fine other than it wont shift unless you let off throttle (as mentioned in earlier posts)......I went to autozone, had codes pulled and one guy says its a servo pack....but then another guy says it doesnt have that.....I swear autozone gets more and more confusing by the second.
I checked fluids and they appear clean (pinkish colored), I did not pull pan and look at filter but seeing as I bought from a autozone manager....and everything in car seemed to be filled and topped off good (no overheating issues either)....and he had a stack of receipts for replacement parts....I was gonna start looking into wiring and hope maybe a bad ground?? even though I havent done this work in forever.....start simple instead of going gungho into the worst possible....K.I.S.S. ya know?
anyways...TIA for the help...I been scouring thru online looking and this was one of the first that said got it fixed without dumping a transmission out.
am I correct in thinking TPS...Throttle Position Sensor? and where would that be located at on this car?

Hi Jim,
If you do a search for all of my posts you'll see a few threads releated to this problem which have further info and photos.
The TPS (Throttle Position Sensor) is located at the side of the "Throttle Body" and based on my experience here would certainly be the first thing to check and replace (if out of tolerance).
I got my replacement at the breakers yard for something like $6 if I remember correctly.
Here's the general location and procedure for the TPS check on the 240SX:
There's two parts - here's Part 1.

The Altima uses a transverse engine (FWD) so, it'll be going left to right, as opposed to front to back (RWD) as shown with the 240SX.
Hopefully this will mainatin the K.I.S.S. principle
The same TPS is used in a variety of cars - mine was sourced from an Infiniti model - you can probably have a look at the cross references on eBay listings for the TPS to see the full list of cars that use the same sensor part number
