I have a 2000 nissan maxima se auto tranny..
I replaced the shift b solenoids because of the p0755 code and now I have some issues. The car drives normal until you give it more gas to accelerate faster and then it slips/revs up. The fluid was clean and red like new before I changed the solenoids. I'm at a lost here.

I put the vb back in the transmission and had the spring go into the right place, im not 100% sure if it is standing straight up. If it was slightly off would that make the transmission randomly rev while driving? It wasn't changing out of limp mode before I replaced the solenoids. Now it does but when your on the highway it randomly revs up when you try to accelerate faster. Is that because that large spring that sits on the vb on top while you put it back in the transmission is somewhat off slightly?
Would that cause this issue? I didn't take apart the vb i only changed the solenoids. When i took The old line pressure solenoid out no springs came out. I removed the old solenoid and replaced it without any spring coming out.
what would make this Rev randomly?
ANY INFO ON WHAT TO LOOK INTO WOULD BE VERY HELPFUL.
THANKS IN ADVANCE

 

Check out this thread. I replaced the solenoids on my 97SE since the Nissan had a "updated" kit that was selling for $127 back in 2002. My issue of hard shifts 1-2 was solved by replacing the dropping resistor. It is mounted behind the stock air box.

P0755 shift solenoid valve b - Maxima Forums

 

I got the p0755 code. The check engine light was on. I changed the solenoids but like I was saying I'm not a 100% sure if the spring that rests on top of the valve body is perfectly inside there. Would that cause the tranny to lose pressure and cause it to slip while accelerating? What does that spring actually do? What's it called?

 

Is there anyone who can help me out with this?
I don't know what the spring is called but it's the one that just rests on top of the valve body while you reinstall the valve body. If it's not in there correctly what are the symptoms of that? Is there a way to make sure it's 100% correctly seated in the hole that it goes into after you bolt in the valve body? Any tips or tricks? Someone please chime in . I need help!!
