hi guys i am having a problem with my ally.
the truck is a 2001 dmax with 186k miles the truck has the edge on level 3 other than that it is all stock.
ok here is the problem when driving and coming to a stop the truck wont down shift into first its like it gets stuck between gears and its in neutral. then after about 3-5 seconds it will slam into first gear. then all is fine untill i have to stop again. the fluid is new as is the spin on filter and i also changed the nsbu but none of those helped. could i have a bad actuator in the tranny? i also read somewhere i should drop the valve body and clean it and replace the pan filter.

any suggestions on what i should do??????????
thanks

you have a trouble code and it has defaulted to get your attention ,and it worked ,get it scanned & fixed,do not mess with the valve body.they are very expensive,reconditioned valve bodies usually suck
