how does a high stall TQ converter effect daily drivability?

i was thinking of posting the same question soon. i would think that around a 2000-2500 stall would be fine for daily, anything higher than that and youre launching at every stop...

not many people have high stalls on here i dont think... im getting one when i rebuild though.

how exactly do they work?

check out howstuffworks.com they have an explanation of how it works. i couldnt explain it any better than what they have to say.

it basically lets you rev higher before you 'go'.

a TQ stall speed should match where your car gets into its powerband
you can get a 2800 stall and it will be just fine for daily driving and make a huge difference, someone has a 3500 and says its not totally streetable, I thought they were getting looks cause it sounds like they are revvin at every stop,etc..

if your gonna do it get a 2800 and call it a day

2000 is WAY WAY Too low
even 2500 is a little low for us, the 2800 is just perfect

do you have one mcgyver? and when you pull the engine, the torque converter is right there. is it that easy to just change it?

and would an entire tranny overhaul be necessary with a higher stall converter? im sure it wouldnt be bad by any means, but is it really necessary. i dont want to pull the tranny if i dont have to.

im thinking between 2500 and 2800 would be a good stall. im taking into consideration this is with stock cam gears. i guess you really cant pick out a converter if you plan on changing cam gears, until you actually change them and dyno it. im thinking turbo grind 14, i think a few on the board has them...

blah blah etc etc.

get the 2800 youll be really happy with it,
and you still need to pull the whole tranny out to swap convertors, but its not really necessary to change to better internals either, your stockers will be just fine, but to build a GOOD a604 you need to uprade to better internals like kevlar clutch packs,etc... that will help each gear grab better/faster which is good

and no I dont have one YET, but Im coming into some money and might just have one hell of a car by years end

use fine grit sand paper and go over the clutch drums. It helps the bands grab. :thumbsup

I know, OLD thread. Is it still true that there's a limit to what stall speed I can run due to having a 1995 Eclipse GS? If so, what is that limit?
Or is there a workaround yet?

pretty sure your still limited because its a 95 with a funky tranny computer.

PM ryan95i4 for info on that. he knows what works/what doesnt for the 95 as far as the stall speed.

Why does it stick out in my mind that '89 Caravans have A604's and less of a TCU than us? Anyone reading as much into this as I am, or am I just a tool?

I had a built atx with a 3K stall in my car before I swapped to a mtx.

At the line, I could build 12-15lbs of boost with ease (s16g), and bring the revs to well over 4K rpm (brake stall). The problem is the 95 tcm sees this high stall as slippage and will put the car into limp mode (2nd gear only). Even while launching 2nd, the car would still light up both tire 1/2 way through second, but...only second gear was available.

The issue with the early tcm's was what it saw as slippage. When brake torquing, your input speed sensor is seeing lots of speed, and your output speed sensor is seeing nothing -- when this becomes dramatic enough, into limp mode it goes. Im told 97+ tcm's do not have this same problem, but then, I dont know anyone who was actually building over 4K rpm and a bar of boost at the line either -- I believe dougie may have been, but its been a while since I kept up here.

I had planned on putting in a 97+ tcm to try and remedy the situation in attempt to salvage at least one track session, but swapped in a manual before I ever got the chance -- one of the few stock parts in the tranny, the OD clutch hub, sheared off and I refused to put another dime into another a604 ever again (now that the a604 is put into turbo PT's, DC has upgraded the clutch hubs -- had this been an option when I built mine, I would probably still be using an ATX, but that was many years ago ;) ).

As far as drivabilty went, the car was daily driven without a problem. the 3K stall didnt prevent casual driving at all.
