Question about 1996 Volvo 960

1 Answer

92 960 2 questions Q1 : transmission (when warmed up ) will sporadically engage into overdrive , in low speeds , then frequently engage and stay engaged into overdrive when stopping (like a manual transmission without disengaging clutch pedal ) have replaced all switches :transmission neutral safety , and 3-way power ,economy and ice mode switch , with no effect on condition . Does need transmission fluid changed ,but was told that would affect overdrive condition Q2 : noticed that hydraulic lifters are getting noisy and oil light sometimes takes more than a half second to go out when engine is started , read somewhere that oil pumps on early 960s go bad( pressure regulator spring ) and was wondering how much time and effort (shop time ) does it take to replace pump . Or actually is it something else causing this problem?? thanks

1st thing to do is run a self test of the trans for trouble codes, sounds like a problem with the electronics, may be a poor trans connector connection or a solenoid issue in the trans.
2nd if the oil pressure is low and by your description it is, don't drvie the car, you will burn out the rod bearings then a new engine is needed, yes it sounds like a oil pump issue, there is no easy pump to change, jack the engine off the motor mounts and it makes getting it out easier. Please give at least a helpful rating, we experts do this for free, just want to help folks like you with car problems.

This is a normal condition, the nag transmission control module needs to see a certain temperature of the fluid before shifting into overdrive this is due to fluid viscosity, if the fluid is too thick
due to cold temps the pump cannot supply enough pressure to fully engage
the overdrive clutch, if it did you would have slippage in overdrive

Overdrive not engage


make sure transmission fluid not too low.other possible causes to your problem could be faulty transmission shift solenoid or faulty input turbine speed sensor or faulty output speed sensor.could have faulty vechicle speed sensor or faulty TPS have vechicle code scan could be many things.

What is the "overdrive" for?


overdrive is just what it sounds like-the transmission turns slower than the engine, allowing more speed with less fuel. It is only applicable in higher speed, low load situations like open road driving, but most modern cars with overdrive will allow engagement at speeds as low as 35 MPH to save fuel. To a point, overdrive is effective for some city driving, but if you constantly do stop and go driving, in city enviornments at speeds under 40, it is best for the engine (and performance) to 'lock out' overdrive.

P1740 code on 2001 ram 1500 tcc-overdrive solenoid . how to test & replace


there is a total of 27 diagnostic steps to follow, but here is some info for you:
SYMPTOM
P1740-TCC O/D SOL PERFORMANCE

WHEN MONITORED
The Torque Convertor Clutch (TCC) and Overdrive Clutch (O/D) will be tested each time the PCM requests TCC engagement in 3rd gear and O/D.

SET CONDITION
The code will set if the expected RPM drop is not achieved while attempting to engage TCC or O/D. This indicates a malfunctioning torque convertor or overdrive clutch.

POSSIBLE CAUSES
- Camshaft DTC present

- P1765 DTC present
- Park/Neutral DTC present

At about 45 miles per hour the overdrive goes in and out once you get past that speed everything is okay.


45 mph is about the speed that the switch is set to engage the overdrive. Typical problem if you know of a good transmission shop they may be able to make adjustments. Unless it is slamming in/out rapidly frequently I would probably ignore the problem.

1996 Nissan Terrano diesel automatic. How and when can you change High to Low ratio? What does the toggleA/T button, which has 2 seetings - power and hold, do? What does the dial which has 3 positions -...


High to low /low to high ratio, you will need to be stopped and the transmission in neutral for this to be changed.
The 2wd - Auto - Lock switch can be switched at any time, as it operates an electromagnetic clutch - 2wd is rear wheels driving only - Auto - is to automatically engage 4wd when wheel slippage is detected (this also happens when turning at intersections, due to the inside wheels having a shorter path to the outside wheels, and can give a binding effect on sealed roads (I don't drive with it in auto on sealed roads) auto is excellent if you get, or expect wheel spin from an intersection when wet, just flick it on before or when you have wheel spin, also on gravel roads, having it on auto will greatly reduce the sliding of the back end, and make the car noticeably more stable.
Lock - this locks the differential, which further reduces wheel spin, when in mud / snow, but this will also make the car not want to turn corners, due to it resisting the different distances traveled by the inside and outside wheels.
A/T switch - this actually has 3 positions, and changes the shifting points of the automatic transmission - the middle is normal - Hold is to hold the gear longer, to improve fuel economy, and not change down (kick down) as quickly - Power has the opposite effect, it makes the transmission change down sooner under acceleration.
Also the O/D (overdrive) button on the side of the Tee shift lever, is to engage / disengage overdrive (5th gear) - never do heavy towing in overdrive, this will cook the transmission and overheat the engine (due to the radiator being used as a heat exchanger for the transmission fluid.
Another little quirk - if the transmission light starts flashing every 40 to 50 km, this can indicate that the wheels are different diameters (a flat tyre, or tyres have been swapped around and the spare is more or less worn than the other tyres), the computer will pickup that the wheels are turning at different speeds.
When cold, it is normal for the transmission to stay in 3rd (2-3 minutes of driving), until it has warmed up, and then stay in 4th for a few more km's (5-6 minutes), before it has warmed up enough to change into 5th (overdrive).

1994 toyota paseo: overdrive problem


I would start with replacing your tranny fluid. black is no good. your tranny should hold about 7 qts of fluid. The tranny fluid runs through your radiator to help keep it cool. If your thermostat is stuck closed your eng coolant won't circulate and the coolant will get hotter inside your radiator. thus making your tranny fluid hotter and breaking it down. After time it will turn black from getting too hot. Let your car warm up to normal operating temperture then grab your upper radiator hose. It should be very warm. If not your thermostat is stuck closed.
