Are you saying its not downshifting when you want to. What do you mean your speedo is stuck?? As in its not working?

Symptoms like your tranny is slipping in 4th gear under a load? check AT fluid, see if it's low and burnt. If fluid looks fine. Could be slipping clutches in the auto tranny, time for a rebuild/replacement. Get an opinion from a tranny guy though, one that you trust.

And replace the cv axle too. It's only like 69.99, and it's hard to diagnose problems with known-bad parts installed.

Not sure what to say on the Tach and Speedo guages. Do they EVER move, from the time you start the car? need more info here...

thnx for the input...well my Tach and Speedo gauge work fine..its just that when the tranny is slip or not egnaging or transfer power to wheel...the engine rev louder but RPM needle in not increasing...it happen sometime on steep freeway around 60mph+..i Check my ATF and its pink and full..
Thnx

possibly needs a rebuild

Is your tranny flashing any codes?

[Specter]

yeah check the codes... that's one messed up problem, almost sounds ECM related

[Accordlx]

no there are no CEL or D4 flashin...everythin seem fine

[NAiL05]

Hmm id still jump the TCU just in case there are codes stored inside you know? It might not be a permanent code but something could be stored in the TCU.

This is just a guess I am throwing out, but could linkage on the transmission be loose so as it isn't engaging D4 properly, and it is getting into Neutral? Just a thought.
