1996 Volvo 960 has shifting problem. Took to Trans shop and they think something is wrong with motor. When shifting from 1 to 2 it seems like the tranny is slipping or dropping down then back up quick causing car to buck. After it gets to 2 it drives normal. No codes are coming up and car runs smooth. If in park I step on the gas pedal pretty quick the car almost dies then revs normally. Doing this a couple times and the car will sometimes sound like it backfires under the hood. Not real loud but enough to hear.

Mine is doing the same exact thing???

it should tell you on the dipstick what kind to use.they may not have change the filter

I have a 95 960 wagon and my seats have circuit boards

That trouble code is the input speed sensor. It is bolted on externally. If you have had any recent work in the area directly above the trans axel, someone may have unhooked it. It is located at 12 o'clock right about the middle of the trans.

A good diagnostician with a scanner can hook up and drive and be able to see the impulse from that sensor. It can be replaced without a major amount of work, however it is a little hard to see. (I think you will find it under the cooler lines, but it has been a few years since I worked on one.

Hope this helps.

It is a sign slippage. Flush and replace the ATF and check for any improvement. Also check the alternator whether charging correctly.

Your transmission is going to fail sooner or later, the whining noise you hear is the the clutch packs in the transmission going out.

Just because your Check Engine light came on doesn't mean there's something wrong at all. Various Mechanical functions are timed by the Manufacture to signify Servicing required.

Sometimes they're set at 50K miles or more, when the light starts going on, all you have to do is take it to an Authorized Service Shop and they Reset the timer. Most places won't even charge you for doing it unless they find something wrong.

its inside the petrol tank,remove fuel gauge sender unit and its on the bottom of that.check for feed and connections first before changing the pump

Codes prob stored in trans control module. I would say problem is gear position sensor is faulty. It is located on the pass side of trans, next to cat. the wiring goes over top of the trans. It will need put up on lift to replace. prob a 3 hr labor job in shop.

maybe you got pennies money stuck in the track if not you got 1 motor for that the motor goes in a assembly in there you have 2 cable a left and a right lock under the seat you probably got the right cale disconnect sometime there stuff that push under the seat and push that cable off if its that just push the cable back in let me know and please if you can take the time to rate this thank you pierre
p.s when you try to put the cable back in dont force to mush
