RPM jumps up when shifted into gear - Toyota Nation Forum : Toyota Car and Truck Forums

ok i am kinda new with these camrys but i am looking into a 93 camry LE V6. whenever you shift it out of neutral the RPM jump to about 1500 rpm.... is this normal for these camrys or has anyone seen this before. please help i need to know before i buy this car.
thanx

well, the question is this.....it jumps to 1500 from what?

typically, since there is no friction to gears in neutral, the rpm's are higher, and once shifted into gear, it drops

it idles normally at about 700 rpm but when shifted into gear it jumps to about 1500. any clue what it could be or if it is a problem?

sorry it jumps up to about 1500 without pressing the gas then settles back down to down to a normal idle.

mine does that, never really thought much about it... automatic transmissions do silly things for silly reasons

thats normal.

I don't have a V6, but it doesn't sound very normal to me. It sounds kind of dangerous.

Does it happen as soon as it comes out of park? What if you slide quickly into neutral?

All this high rpm will do is put abnormal wear on the tranny.

yeah. mine does the same thing. Just hold that brake pedal down hard so she wont go anywhere.

Mine does it more from park but it does it from neutral a littl.e

its normal, ive got a 92 v6 and it has always done that

karazy · 09-23-2004, 03:56 AM

I can't help but doubt the idea that this could be normal. I'll become a believer if someone can explain the logic behind this one.

Why does it happen? There must be a purpose.

How does it happen? Which sensor(s) are involved.

PS- Does the tranny ever clunk into gear, forward or reverse?

Luckynumber5 · 09-23-2004, 07:09 AM

when the transmission shifts into gear it requires more torque for the engine to keep turning the tourque converter, my 92 v6 is getting old and i will say in the earlier years it never really did this, but with wear and tear on the tranny and engine the ecu may just deem it necessary to increase the idle for just a little bit until things even out

karazy · 09-23-2004, 01:29 PM

If that is the problem, why doesn't the ECU just increase the fuel to maintain the RPM. Even the high idle valve only brings it up a few hundred to compensate for added load, but that's just because the alternator doesn't work at capacity at low RPM.

PS- I'm not trying to be an idiot. I'd just like to understand.
