700R4 durability test - Third Generation F-Body Message Boards

IrocNrollCamaro · 08-31-2006, 01:08 AM

yeah, so i pretty much blew my T10... i thought they could handle quite the punishment... but i guess four hundred fifty four cubic inches is too much for it to take all at once...

Was wondering how many ft/lbs a 700R4 from an 89 305 camaro can take, and what i would have to do to put that bad boy into my standard car.

reason im asking is cause i dont have the dough to buy another T10, cause theyre bloody rare here... and i dont have enough for a tough enough 5 spd, or a 6 spd... auto wrecker said i can pick up a 700R4 for about $650. i want the over drive cause 454+3.73 = gallons to the mile.

700R4 are really good, especially if you add a shift kit and a corvette servo that thing would fly and yeah it would handle your 454 depending of the condition of the trans.

Add a loose, smaller diameter converter, with lock-up and it might have a chance to stay alive. I killed my 700r4 with a 305.

You'd have to cover the hole in the floor for the manual shifter and mount an automatic shifter, change the console, plumb in a transmission cooler and get the torque converter clutch to lock. I don't know how long I'd expect a stock 700R4 to last, though.

a stocker won't last long, but a proper built 700 can handle a really stout 454(ask me how I know

) PATC's(raptor) website/techs will answer all your questions on what you need to make it live.
- don't waste your time with the vette servo. I use those for stock rebuilds. Performance 700r's should always have the billet servos.

Properly built 700R4s start to get expensive, unfortunately.

Yep, I have $1,100 into PARTS ONLY on mine and I still would not trust it for much more than 425 HP/450 TQ reliably.

hmmm, well i need to scrape up some cash, cause this was my daily driver, im driving my bros unmuffled civic

... how much would a TH350 or 400 cost, plus all the parts to convert from standard to auto.. i have no clue waht all id need, so a little list would be appreciated :P my shop teacher said i can do it all in class so that will be nice

You could build about 3 TH350s for the price of one 700R4. You'll need the transmission, flexplate, torque converter, transmission cooler, vacuum line, kickdown cable, some sheet metal, a 3 speed shifter and a console top.

IrocNrollCamaro · 09-01-2006, 12:59 AM

hmm... not bad, that shouldnt push me over $1000 would you think? and... sheet metal, whats that for lol

Apeiron · 09-01-2006, 01:01 AM

To cover up the gaping hole in the floor where the manual shifter comes through so you can mount the automatic shifter.

Oh yeah, you'll need a shifter cable and grommet, too.

IrocNrollCamaro · 09-01-2006, 01:02 AM

ahh that makes sense... well i was gonna put a mega shifter and a trans-go kit before i stick it in there, so u can cross a few parts off the list
