kc8oye Posted September 18, 2007 Share Posted September 18, 2007 well after bolting in the 700r4, and trying to find a driveshaft at leo's that was short enough, and his shortest one being 1/2" too long... I found a local machine shop that could shorten my old one for me. Cost me $61 to have them take 3-1/2 inches out. I could have had it balanced for another $80 but I'm not going to do that just yet. (If I have problems I will) I didn't relize they needed the ujoint caps to machine it, (left them at home for safe keeping) so I just had them put a new ujoint in the back for another $20 it was problaby cheaper then driving home to get the old caps!

kc8oye Posted September 18, 2007 Author Share Posted September 18, 2007 CHHHHHHHA CHIIIIIIIIIIIIING!!!! FINALLLY!!!! _SOMTHING_ went right!!! I'm glad I went for that extra 1/2 inch too!!! I had the machine shop take 3-1/2" out of the driveshaft, and it fit right in like it was meant to be there that was $80 well spent :> $61 to shorten the drive shaft, and $20 to have them install a new ujoint.

Kevin Wiles Posted September 18, 2007 Share Posted September 18, 2007 how much of your yoke is on the shaft of the transmission including the little bit of shaft that sticks out of the tranny? total touching length? Quote Link to comment Share on other sites More sharing options...
Andreas Posted September 19, 2007 Share Posted September 19, 2007 Tim, You will now have to play with the 700 R4 TV Cable, which is important. Improper adjustment and your tranny will break in a hurry...

kc8oye Posted September 19, 2007 Author Share Posted September 19, 2007 I have a factory service manual for my '86 astro van with a 700r4 and it's really very simple, release the locks, push the cable all the way in, pull the throttle wide open, while holding it there, lock the cable in place. my '89 cutlass also uses a TV cable.. tho it's a 440-T4 trans the trans shop apparently forgot to set it, so I ended up doing it myself after the rebuild. been there.. done that I still think the Vacum modulator and kickdown cable is a better setup Quote Link to comment Share on other sites More sharing options...
kc8oye Posted September 19, 2007 Author Share Posted September 19, 2007 kevin, I think I've got about an inch of yoke exposed when the car is sitting at normal ride height. I'm actully kinda wishing I had only 3" taken out. I forgot to take into account taht the drive shaft slides into the trans as the rear suspension extends (axle drops away from body) and pulls the shaft out as it compresses, due to the arc of the control arms.. oh well. if it appears to be a problem, guess I'll buy another driveshaft from leo and only get 3" taken out lol Quote Link to comment Share on other sites More sharing options...
680HPStroker Posted September 19, 2007 Share Posted September 19, 2007 I would have had the driveshaft balanced for if nothing else piece of mind. Around where I live for a few pennies more than what you spent you would have had a driveshaft made for your application with heavy duty Spicer u-joints. I believe mine was $150.00 complete with balancing. The DOM steel they used is much stronger than the OEM stuff. Just something to think about for the future if you really want to get crazy.

kc8oye Posted September 19, 2007 Author Share Posted September 19, 2007 i considered having one made.. but the best I could find was $300+ for aluminum ones. when I get that other u-joint done, I'll problaby just get it balanced 'just because' Quote Link to comment Share on other sites More sharing options...

kc8oye Posted September 20, 2007 Author Share Posted September 20, 2007 yeah.. $250 is a lot more then I want to spend right now on somthing I don't _really_ need at this point. I will definately consider that tho when I start adding h.p again :> Quote Link to comment Share on other sites More sharing options...
