earlier today, i driving to MD everything was fine. i was going like about 60 or so and suddenly my rpm jump into 4500 rpm. i always have my overdrive on. i started to think it was my transmission slipping, but why would it slip all the sudden? right now i'm in stress with the problem. have this happen to you before? please help me!

Justinizme

Does your overdrive display work on the dash? Does it light up on the cluster and say it's engaged or disengaged?

not to jump in

but mine jumps 2nd sometimes and my o/d lights up on dash, and plays peak a boo with me also.

it does engaged and light up. it won't shift into overdrive period!

Justinizme

Well, only advice I have and save some money would be pull the pan on the transmission.. Change filter/screen, check fluid for any metal/chunks. If nothing there, take it in, get the transmission flushed OR get it serviced, unless you can do that yourself.. And the reason I asked if the light worked/didn't work, is if it stayed on or stayed off, it could have blown a fuse or the wiring could have been faulty, keeping it from shifting into o/d..

That sounds like a loose ground to me.. or loose wires in general. But hey, i'm just giving my two cents..

I see thank you!

I will check under the car tomorrow.

i had everything done about 2000 miles ago! i don't know it bugging the hell out of me.

Justinizme

What did you have done? have you checked relays/fuses under the hood and in the fuse panel under the dash? Are all the other gears working and shifting smoothly?

it shifts in all gear 3 gear and won't go on overdrive. tomorrow i going to check the fuse to see anything is blown out.

Mine doesn't work after the usdm 2jzgte swap and I cruise around at 4000 rpm. Wish I knew how to get OD to work again

Let me chime in on my own O/D tranny problems....I'm almost certain that for me, it's a sensor going bad or maybe a loose wire or bad ground...The O/D off indicator light comes and goes as it pleases at random and has a distinct "Flash,pause,flash,pause,etc..." pattern...But the car shifts into overdrive just fine,There's a notable change in rpms when I switch the O/D button between on/off and the car shifts smoothly between gears and doesn't drive like crap. I will check the fluid levels and look for any loose wires in the immediate future.

Oh and for the record, You don't really have to drive with the O/D button turned on and engaged, The overdrive feature is essentially for fuel economy...Don't quote me on this next part but, But I believe you can drive "faster" with the O/D turned off...try that with the "ETC PWR" button to boot with it.

Justinizme

Well the ECT button is basically just for shifting times.. Lengthens the gears.. "Electronic Controlled Transmission".. So, if your boosting I could understand the need for the longer rpm, but idk about the stock engine.. The factory essentially made it shift to stay in it power band. Keeping O/D off, I have never noticed a difference in speed, but will make 3rd gear stay engaged longer. So, Idk LoL

yea that's my problem! i can't stand seeing my gas just guzzling on 4000 rpm. we really need a solution for the problem.

So are you on a stock ge motor or do you have a gte swap?
