Transmission Slipping?

[jarred15801]

Sometimes when i startout from a stop and just giving it a lil bit of gas, for example going through a parking lot or congested stop lights. my car seems to go fine through 1st gear and then when it gets to about 2000 rpm's it tries to shift into 2nd i believe and it's like it doesnt grab because it just revs to 3000 rpm's and then catches and shifts and the rpm's drop back down. then the rest of the gears are fine. it doesn't do it all the time either. anyone ever have this problem? or any idea what it is?

i just bought the car with 99k miles on it and ive put on a thousand. i don't know the last time the transmission was flushed so im getting it done next week hoping that will fix it.

Guess you now know why previous owner sold the car...he knew a $2500 repair bill for a rebuilt transmission was heading for him. Check fluid level and color, but chances are if it is already slipping, it is too late for any miracle cures in a bottle or flushing to help-prepare for the lube and rearend job.

Shoot me an e-mail I have a transmission if you need it.

Appearance and smell of fluid? White paper towel test?

Might consider adding an ATF cooler at the same time.

I hope it isnt an original transmission to one of the 3 super high mileage Q listed in your signature....nothing like replacing a old worn part with another old worn part!!!

I'll check the color of the fluid tonight. I don't believe that's why they sold it though. because it didn't do it at all for the first 500 miles that i had it. And it doesnt do it all the time or even that bad when it does. When i accelerate heavily it does not slip at all. thats why i don't even know if slipping is what it is doing. thats why i asked the question.

This post is kind of rude-especially since you have little info about my parts. However, if you'd left the off then it could have been tolerable and maybe even funny.

I'm sorry, please forgive me.

Under heavy accel it doesn't slip? sounds like a low line pressure issue at low throttle position. Find the dropping resistor and unplug it, if the car has one. Nissan autos do. when you unplug the dropping resistor the TCM goes into fail safe and maxes out line pressure. It's gonna shift hard as crap but if it holds under light accel then youve pinpointed the prob. Your still gonna need to rebuild. This may keep you on the road a little longer however...goodluck

You don't sound very sorry.

I agree that this doesn't sound like a worn transmission but rather a component failure. Especially with only 99K on the transmission.

I have almost the same problem, but mine only happens when transmission is cool (usually just the first shift), and only at higher torques. I've had this problem for 2 1/2 years now - in the face of a $4,000 repair bill (homes and gas aren't the only expensive things in SoCal).

So long as I remember to baby that first shift in the morning, she shifts smooth and solid. No other shifting problems...

I've got a flush and filter change next week, but not expecting any miracles.

I'd live with it if it doesn't get worse.(Oh, that's right... I have)

Well, you could try waiting for the car to reach operating temperature before......well.....operating it.

Do the pan drop and filter replacement, new O ring, gasket and one time use bolts. Use M1 with 6 oz. of Lube Guard Red. You might be surprised.

Where do i find these resistors? and how do i find the "dropping" one?

[carmo]

on older maximas youll usually see it on the side of the engine bay around or on one of the shock towers. Theres just a couple of wires running to the connector.

Mine is like that. In the morning it woun't go into drive "D" until it warm up. After 2 minutes, everything is perfect. Sometime I move if to 3 and when it warm, shift back to drive. I have been doing that for about 3 1/2 years with no problem.

The dominant concept here is "operating temperature."

Yes, many don't realize a 3-5 minute warm up in Summer can be a 10-12 minute warmup in cold winters.

The TCU will not allow the AT to operate WELL until the ATF reaches 140-174F to protect the AT from owner abuse.

Is the low line pressure issue a fixable one? I think that could be the culprit to my AT's shenanigans. Light acceleration is cool, as well as load. But medium "daily driver" acceleration and my 1-2 shift is a neck snapper/drink spiller/big PIMA.
