you might need a new one soon. but first check your transmission fluid.
No it will shift slow.
balls. balls will slow shafting
I would check the transmission fluid, if the level is good i would get the transmission diagnose you may need to remove or replace the transmission.
dirty tranny fluid
Very slow or fast transmission speeds become from what combinations of hardware and software?
Likely, your shift linkage from the carb to the tranny has become disconnected. Or, it's designed that your engine is supposed to slow so the transmission can safely shift gears. I say just live with it. It's not causing any problems.
My V10 2001 Dodge slow shifting was solved by replacing the catalytic converters. The ECU was detecting load/stress, like pulling a trailer up a hill. So it signaled to the transmission to not shift up to the next gear. After CAT replacement the shifting was fine. For me this was NOT a transmission issue.
there is no fuse that makes the transmission shift the transmission shifts on cylinoids and rpms
Too fast or slow of rpm for gear your trying to switch into A bad or going bad shift synchronizer
One of the reasons a transmission might not shift into overdrive could be a problem with the belt drive inside the transmission. Belt drives can be stretched over time. Another reason could be that the transmission fluid is low or very old or the filter is clogged.
VERY CAREFULLY.
To answer directly, yes. A bad MAF sensor can affect a computer-controlled transmission if the transmission control computer uses the MAF signal to determine shift points.
