can transmission issues cause -reduced engine performance code?-
 

2004 xc90 115k miles 2.5 t
everything works great until you get on it to pass and loss of power
reduce engine performnace lights up on dash runs like crap
pull over restart everything is fine no check engine light
engine will rev freely to 5500 no funy noises
power brake to 4000 rpm no noises or problems
My question can a transmission sensor / problem cause xc90
to basically go in limp mode -reduce engine performance?
thanks

Sounds like a misfire or a big turbo leak.

Not usually.
