My 2k2 Auto jump 200-800 rpm when change to secong gear... why? Any problem with my tranny or no? The dealer said me that its normal...

 

what do you mean jump??

 

Ok... i'll try to explain you... my rpm is 2500 and when change to second gear it jumps from 2500 to 3000rpm and change...

 

I never paid attention to it but sometimes mine does that too but no problem so cant complain. Try this next time your driving (I dont know if the 2k2-3 does this) going 40mph turn the overdrive off and casually accelerate up to 60mph and keep an eye on the rpm guage. On mine around I think it was 2800rpms it drops back down like 500-600rpms and continues as normal after that. I know the torque converter is the one causing it to do that, nothing is wrong but just wondering if the 3.5's do that as well.

 

I have a 2000 SE and my automatic transmission exhibits these same exact symptoms. It's called slippage.

Here's the TSB for 2000s: http://www.punkdork.net/max/tsb039a.pdf

I don't know if there's one for 2k2s? Try searching.

It's been discused on the forum before. The Nissan stealer always says it's normal, but my Max did the exact same thing. The problem got fixed after I replaced the tranny fluid with Mobil One synthetic ATF. Big dif.

 

I think thats part of this "tranny lag" that the dealer too told me was normal

 

My 2002, with 20,000 is at the dealer right now getting a new trans installed because it was slipping.

 

If i want to change the tranny fluid how many boxes of mobil 1 I have to buy? Or can i tell my dealer to change the tranny fluid with the mobil 1? or can my dealer do it this?

 

My dealer did this for me and I provided the Mobil1 ATF. My dealer used about 13 qts for a complete tranny flush. I don't remember what it cost, but he deducted the cost of the ATF from their standard charge for a tranny flush since I brought my own.
