700R4 CONVERSION

[STROKERBU]

I am doing a 700R4 conversion on my Malibu that currently has a TH350. I was told that the 700R4 is 4" longer and that I had to get my driveshaft shorten. The question is, is there any other G-bodies out there that came with a factory 700R4 that the driveshaft would swap out in my Malibu? Maybe one of a Grand National? #-o

No. Grand National and Monte SS came with 2004R, not 700R4. 2004R goes in without driveshaft mods, 700R4 doesn't.

Hope this helps.

Thanks for clearing that up. Anything else that would fit? anyone?

The driveshaft has to be shortend about three inches. The trans mount hole on the crossmember may have to be cut or drilled bigger. Im also going to put a 700R4 in my 81 Malibu this summer.

nope.. i had to have mine shortened and change the crossmember to install mine


going to have to shorten it again since im putting in the 12 bolt.. but will def have to do those 2 mods

Ok, Got the transmission in. 3 inches is correct as far as how much to shorten the driveshaft. The crossmember needs to be modified. Thanks for the help guys. Will keep you posted.

Got the driveshaft in today. 3" shortened was perfect. The crossmember was a easy modification. I cut about 1 1/2 inches off the mounting tab and drilled new holes of what was left and ovaled the holes. It fit perfectly. All I have left to do is hook up the detent cable, the lock up switch for the coverter, fill with transmission oil and get a new shifter. The Z-Gate I bought and the star shifter I had from B&M will not work cause they are made for a 3 speed transmission. I need to get a shifter for the 700R4. A 4 speed shifter. Hopefully the local part store has one in stock. I will let you guys know how this monster transmission works. It is the most complete conversion kit I have seen. Let's see if everyone will "EAT MY SHIFT" like they claim. dancin_banana.gif

Did you modify the stock TH350 crossmemeber or one from a 200r4 ?

I would like to know because I took out a 350c trans and crossmember, and replaced it with a 200r4 trans and crossmemeber. Now I am looking at a completely built 700r4 and I am wondering what would be a closer match ??

thx much
