Ok, my tranny just started slipping from first to second when it's cold. I've found a lot of stuff on here about the slippage on the 2000 model including TSB stuff. I don't want to be redundant, but I can't find anything on whether my VIN qualifies.

Also, my car has 76k on it, is it still going to qualify? Are the limits on how many miles before they stop fixing it?

Any help would be appreciated.

 

I just replaced my VB with a stage II from maxtuning.

 

Is something like that or the VB going to help mine at this point though? I'm still stock and I think I'm about to have a problem.

 

Have you done the Full Tranny flush, if not it is time to do it..... warranty, only if you have an extended one...

 

Actually, I was having no problems at all and decided at 76k I would do a tranny flush with a T-Tech (full flush and fill). It wasn't until about 2 weeks AFTER the flush that I started having problems with the shifting.

Anyone got anything they can suggest?

 

I cant tell weither its my tranny or something or my maf, or coils. I just had the vb mod done and had the silinoids changed. The car shifts fine, Its just when im going slow the car doent seem like it wants to go. If i floor it, then it takes off and goes but before that it wont. What the hell is going on man..i really dont understand... to better explain myself the pedal is almost half way down. and it will not pickup fast enough but when i floor it it will go and it will shift fine. Whats the beef??? any idea???

 

bamasae, bulletin covered only for powertrain, 5yrs or 60000 miles.
VB mod may not save you if its occuring when cold, your friction surfaces may already be cooked from lack of transmission fluid changes or heavy right foot action. The fluid you used may be too thin to build line pressure. You should switch to Nissan D-Matic or a Synthetic ATF, possibly with a friction modifier like Lucas Oil Additive.

Lontar1, rarely does an extended warranty cover a transmission, at least not a Nissan Security Plus one, after powertrain of 5/60K, you are on your own, unless you had a trans replaced just before that period, where Nissan has a parts warranty for 12/12K.

Nocturnal, sounds like a normal symptom to me. at 20mph you could possibly be in 3rd gear in an auto, and by the time it reacts, you may be at 35-44mph which is above peak tq rpm and the transmission will stay downshifted in 2nd and at that speed its low in the range, and won't go into 1st for that instant power on tap if you do the half throttle way. Hammer it at 20mph, and she'll kick into 1st gear. Normal symptom.

 

Thanks Nismo, that's exactly this kind of info I needed. I'm gonna do the the switch to the Nissan D-matic right away and pick up the Lucas stuff as well. I'll give that a shot and keep my fingers crossed, I don't have the funds to drop on a tranny.

Thanks again,

Mike

 

if the transmission is slipping and have done a transmission flush, is the only cure a rebuild? or a new transmission?

 

Plan C) Used tranny

 

So your assesment Nmex is that it's a done deal? No saving this one?

 

?????your saying my tranny is fine??????

 

Where would you find the Lucas additive from?

 

Well, I switched to the Nissan fluid and added some of the lucas stuff. It seemed to help a little, but not a cure.

When I take off nice and easy, it shifts out fine, even when cold. If I push it even a little, it slips between first and second. If I push it hard, it will stay at red line for about a second and a half before it actually shifts and then a noticable flutter between second and third. Even when it's warm, I'm seeing some symptoms.

I'm out of warranty, so my questions are: 1) Am I toast, so go ahead and get a transmisson for this thing? 2) Should I have mine rebuilt, buy a good used working one that hasn't been rebuilt, buy a newly rebuilt one, or buy a new one?

Any help or advice will be much appreciated.

 

:attention Ok, maybe it should be obvious what my plan of action should be but...
I have a 2k with 42k. It exhibits the delayed shift first to second especially when cold when I get on it. (which is rare.) I bought it from an older couple and I baby it. I had planned to do what the tsb said, do the solonoids and the tcm. Also flush and fill with original fluid.
Is this the correct course of action?
Still has stock fluid in it.
afraid to change to aftermarket hearing horror stories about "thinner fluid" causing problems.
The shifting is not at all bad otherwise.
Preventive maintenance if possible.
Please advise you experienced guru's!
Thanks

 

Bump, need a look please at above

 

Same symptoms here, try a total fulid flush. I had my VB replaced VIA a TSB last winter. Helped for a while but the shifting issue is coming back slowly. This issue has been around here for a while. I still don't know if the problem is with the VB or the tranny. I'm thinking about another fluid flush with mabye the Lucas oil additive and see how that goes. Anyones thoughts about the Lucas Oil product please chime in...

 

I've gathered that the solonoids do not solve the problem totaly and you must do the tcm or its not worth it.

Any experinces from you 2k 2k+1 with the mushamatic?

 

If you do a tranny flush sometimes it does more bad than good, reason being if the tranny is old and almost shot it needs that buildup of gook in there. Your flush washed away all the gook like it should have but YOUR tranny needed the gook. IMO there is no treatment that will help it now just baby her and get as much out of it as you can.

 

Why would an otherwise good transmission with 42k on it be shot? I know the valve body needs to be replaced to firm up the sift between 1st & 2nd under 3/4 thlottle. but otherwise it shifts fine and has been babied.

Why would there be a tsb to solve the problem if the tranny is bad no matter what?

 

I firmily believe the flush is what killed my tranny. It was perfectly fine before the flush and then it started craping out afterward. Of course it had 76k on it when I did it. I wouldn't recommend a flush with that many miles, I think it tears up some things with the pressure when a transmission is five years old and has this many miles.

 

anyone know what a rebuild runs on average (installed)

 

I had a Acura Legend and I put a rebuilt tranny in it and it cost me approx $1200 installed. And Pull10k just giving you my opinion!!

 

Try Chevron ATF + Lubegard Black = NissanMaticD fluid.

how DexronIII is changed to Friction Modified NissanMaticD fluid. I have the above combination and it works like a gem.....

Needless to say, if you really intend to only use NissanMatic fluids use the NissanMaticJ (this is friction modified) which is used in Infiniti I30's, boy the shift changes with J fluid is great, I happened to sit in my friend's car and it was a marvel, I could hardly notice any shifts. Good luck....
