Transmission and RPM

[BrianD]

Can anyone tell me what RPM my engine shud B at in my 1998 pathfinder when driving at 115 KM or 70 MPH pls. ?

I was told by my local reputable transmission shop that my automatic transmission shifts into all 4 gears but not locking up and, is therefore, revving higher than it shud at this speed.

It runs at 2,300 - 2,400 rpm with Michelin LTX 235/75 R15 tires.

It mysteriously and suddenly was down a liter of fluid last week - which started me looking into why.

No leaks into the rad or onto the ground.

It still shifts fine but I wanna know if it's working like it shud cause I'd like to save some fuel if possible.

After coming back from the tranny inspection, the guy said there was some corosion on some of the contacts in the electrical connections and that it is now at 98% lock up - but I see no difference.

Thanx in advance.

Did you check the fluid level properly?

 

1. Drive around for 10 minutes in the city after the transmission is at operating temperature.

2. Park on a level surface and apply the parking brake.

3. With P selected, shift through every gear and return to P.

4. Pull the transmission dipstick with the engine idling, wipe it clean, reinsert it completely, and read the level. It must be within the notched area labeled "HOT". Check for fluid contamination after wiping on a paper towel.

 

 

The fluid should be red, and not smell burnt.

 

Sorry, I don't know the answer to your RPM question since my Pathfinder has the VQ35DE vs. your VG33E.

I have 31x10.5x15 tires & I think mine runs at about 2200-2300rpm at around 70mph. I won't drive my truck until the weekend so maybe someone else can be more accurate.
