the problem i am having is its a auto and the torque convertor is shifting to soon.
what convertor would be good?

and what type of hp should i be making?

 

maybe i didn't read this right or something but the torque converter isn't what shifts. the torque converter can be compared to a cluth in a manual tranny. i would try and find a t.c. with about a 2500RPM stall speed or around there. no idea on your HP though sorry

 

The tranny is shifting to soon so i need a torque converter with a higher stall. Sorry for wording it wrong. What torque converter would work best or off what car would be have had one that I could use. I read that the one off a 4cy s10 would be good. But what year s10 would be the best.

 

torque converter isnt what you turn to when you have early shifts. if you need a higher stall speed you turn to a different torque converter. have you read what a torque converter is and what it does?

 

I know what a tc does
The car is shifting to fast at low rpms I just want to know what would be a good tc for the car
If I shift manually by going 1st 2nd drive the car runs fine

 

are you sure?
have you adjusted your throttle valve cable properly?

 

yes
lie i said if shift by going starting in 1st then going to 2nd then drive the car runs fine

 

so you are sitting at a light, you give it full throttle and the car shifts too early? like say it shifts at 4000 RPMs when you rather have it shift at 5400 RPMs?

 

yeah it will get to 3 gear way to fast so its really bad from a stop

 

at WOT what RPMs does the engine shift at? if its shifting too early then it sounds like a TV cable adjustment to me.


so if you manual shift it everything is fine? i need a higher stall TC and manually shifting does NOT help out the low stall speed i have.

 

dude thats not the torque converter. try to get a shift kit or like he said check your TV cable. what RPM is it shifting at?

 

i donot know right this min what rpms it shifts at but its not just on wot.if i manual shift it everything is fine

 

its not your TC

 

ok this is what a torque converter does-
if you hold the brake with your left foot and give it some gas with the right, the stall speed is the rpm that the engine will go to until the wheels break though the brakes and you start smokin your tires. it has nothing to do with the shift points of the tranny whatsoever

 

One thing no one has mentioned is the governor. This plays the biggest part as to when the tranny shifts a wot. The TV cable effects when and how hard the tranny shifts at part throttle and wot. If you have changed rear gears then the tranny will shift sooner because the governor is telling it to, the governor is accually shifting tranny at the same rpm it did before but your not going as fast as you would be with the stock gears.

it was the tv thanks

 

thats what i thought it was, glad to hear ya got it worked out

 

You may still wish to adjust the governor. At WOT open throttle it is probably going to shift a little too soon since its tuned for an engine that red lined at 5000 rpms. That cam should redline closer to 6000 rpms. A V6 700R4 governor may make it run better and then adjust from there.

 

OK ... you guys got the interest of a REAL car idiot now! LOL

Can someone tell me where this govenor is located, and how one would adjust it? I'm a newbie - ecspecially when it comes to transmission anything! - and just wanna learn.

Thanks.
