I need help. Been using nephew's 06 maxima while my 07 SL sits in yard. Making payments plus full cov ins. Will move in R but not D. RPMs sluggish in D but no other gear. Rev to 2000 and engine starts surging. Have gotten multiple codes along journey. Last one was p0868 with no mil. Fluid been changed not metal, fluid level spot on. Any ideas?

This is from Murano,same tranny prob, hope this helps, you might get it fixed for free if it's a recall, good luck bro. Show em this.

 

If you have less than 120k you might get out free

 

Outside ext warranty. Not sure if that would fix it. Has changed since problems started. Have had valve body out when replaced press ctrl solenoid b for P0746. Tested everything on vb for resistance and all good even old solenoid. Replaced vias solenoid for P1800., coil pk 2 for p0302, and let an idiot replace front 2 o2 sensors after he sautered broken wires to back of ipdm now cooling fans don't work on auto active test. But whn brought home did run like a scalded dog and shifted fine. Started having a prob after slow down to turn, then felt like engine brake on and rpms high whn pushed to go. Stopped, hasn't moved forward and rev to 2000 rpm in drive engine surges like I am pumping gas. Runs and moves good in R n revs fine in P & N. Have gotten IAT sensore code, output speed sensor code, can comm code, stepper motor code, O2 sensor code, and etc. Have a flicker that eventually goes out on pass side headlight. Feel like electrical after replacing high pres pwr steering hose. What u think?
