revs drop when speeding up

[Red94Svx]

when im driving say 50 mph and i step on the gas the revs drop about 200-300 revs and goes up.... why? i don't understand lolz as to my knowledge my car has been doing this since i got it but never really put alot of thought into it until now?
is it a transmission problem? (that ='s bad lolz)

It's your torque converter locking up...

Your transmission is fine, have a nice day.

No fix needed, normal operation of an automatic transmission with lockup torque converter.

will that make the shifts harder? cause sometimes i get hard shifts with me trans.?

The shifts being harder could be related to the TPS, or possibly other issues. Do you happen to have a check engine light on ever, or otherwise the "power light" flashing at startup?

[Red94Svx]

yes, the check engine light comes on sometimes but its more of just a flash and then off... no power light blinking tho
what is TPS?

[1986nate]

Check the codes for the engine first following the instructions in the how-to section of the forum and find out what the code is. It should show a stored code even if it just flashes and shuts back off.

TPS= throttle position sensor and if it is not reading right for a couple of reasons, will affect the way the transmission shifts. It also does not always throw a code.

so how expensive and hard of a fix would that be?
because some shifts are hard and some you you don't even relized you just shifted lol...
but anyways my svx is a FWD
does that mean every svx drops the revs like that when speeding up?


edit: what code how to am i looking for ? TCU? (maybe a link )
