downshifting problem

wannarace928 · #1 02-08-2007, 03:19 PM

Well my car developed yet another problem. It is already getting a new engine, but today while out driving it, it would allow you to get up to speed, but if you try to step on the gas to go faster, it wont downshift, it just revs the engine up.

Is this a transmission issue? As in tranny is on its last leg and ready for the scrap yard?

It would appear that when you accelerate the transmission slips and as you are expecting a downshift,(kick down?) you are applying full throttle.

This certainly indicates a transmission issue. More detail will help members to give you further advice.

The RPM's go up. But the car doesnt go any faster or maybe goes 1-2mph faster, it does not loose speed, it just doesnt gain it or doesnt gain very much anyways. when you let off the gas and SLOWLY give it gas, it will get up to the speed you want (as long as it doesnt have to downshift it is ok). If you go from a stop up to 65mph as long as you are not pressing too hard on the gas it will do it perfectly as if there is nothing wrong, but if you try to do it quickly, it cant do it. I have not tried to press the gas all the way to the floor but just enough to get it to try to downshift to merge in with traffic. It definately seems like it is slipping.

sounds like what just happened to our car. budfreak1 can also do a transmission...but i'm first...

This weekend. it's just one thing after the other. unbelievable. my heart goes out to you, as i am in the same boat. but have just used my last resource for the transmission, so i really don't know what i'll do after this. i am so sorry that you also are going through this. all i wanted was a car for my son... a car that would be safe and good for him. our spirits are done.

Don't worry, All spirits will be renewed when I'm done.

(And your son is going to filp over the 4.44's

) And don't you worry either Wannarace, She'll be as good as new when I'm done.

Well I definately trust your judgement, and cant wait for the engine work to be done.
I dont know what exactly I will do if the tranny is going bad.

Manual maybe? 4.44??
This car is really really really pissing me off.

okay, so seriously. I know what ballet flats are, but what exactly is 4.44? I really have no idea. really. what is it that I had?

4.44 is the gear ratio in the front and rear differentials. The higher the number, the faster the car accelerates and the better it will climb hills and etc.. Our stock gear ratio is 3.54, So by going to 4.44 you get much more power to the wheels and accelerations improves greatly. Plus it is cheaper to do than a stock tranny most of the time.

Think of it like a 12 speed bike. The higher gear you use, the harder it is to pedal and accelerate. our stock gear ratio is like the top gear(12th), and 4.44's is like 4th gear.

4.44's for the win. MUCH cheaper than a manual conversion and MUCH easier.

Check your TPS setting before you start talking replacement tranny. It affects the shifting and might feel like your tranny is going.

The 4.44 trannies are more readily available and less prone to failure than the stock SVX tranny. Tom (svxfiles) pioneered the 4.44 swap and has done dozens. Everyone who has had them installed seems to be thrilled with them; I can vouch for the fact that they do "launch" from a dead stop much more than the stock tranny. (I've almost hit other cars when pulling out of parking lots because I wasn't expecting it to move that quickly.) The only downside, in my opinion, is that the RPM's are higher in every gear. I don't particularly like the sound of a 3000 RPM engine at normal highway speeds, but Tom loves it. We have 4.44's in 3 of our 9 SVXi.

BTW, one of the "dozens" was Budfreak's.

thank you for explaining that to me. it sounds awesome! don't get me excited about this car. i have to sell it, but now it sounds like i want to keep it. and here's the confused face again ....

Has anyone experianced any engine related issues running the 4.44?
Since it runs a higher RPM I am assuming it is a little harder on the engines.
Should you do anything different as far as maintenance on either the engine or tranny?

The EG33 is a beast....don't worry about it...it can handle it.

Yes it does rev higher for the same road speed, but the engine is under less load, so you don't have to use as much throttle, to do the same speed.

Exactly what he said.

Like I said, Think of it like a 12 spd. bike.
Is it harder to pedal in 12th gear(3.54 gears) or 4th gear(4.44 gears)?
Yes, your legs(The engine) will be moving faster in 4th gear, But it isn't as hard to get moving or stay moving as it is in 12th gear. I actually saw an improvement in my MPG after going to 4.44's. I average 21 MPG now.
