Anybody ever tap and die a servo plate on a 700r4 to install a 4th gear lock up soliniod/kit
on a non electronic van?

The 700r4 tranny is installed and working now, but it would be nice to lock up the TC on the freeway. Im just wondering if its worth it?

i m interested in the 700r4 also.was it a easy install

kind.of a bitch,
first my old flywheel had to be changed
because
it was about 2 inches to short from reachING the starter.

then the drive line had to be shortened by about three inches.

then you have to weld up / fabricate or buy
A NEW/modified tranny bracket.

i bent the tranny mounting brackets u tabs flat, on one side
and welded ON a LONGER L bracket/EXTENSION
then,
i RE-used the old stock CROSSMEMBER & bolt holes.

i can take pictures if you want.
havent instlled the 4th gear lock up kit yet.
but i like the 700r4

Im swaping in a 700r4 soon. I'll post how it goes.

I have been thinking of doing this too and am interested how it works out for ya both. Mine had a 700r4 in it beore I got it (Guy probley blew it). It still has the drive shaft (Looks like its going to fall out) and mount for the 700 but it has a 350 with a stage1 on it right now.

I want....No I need fourth and O/D man!


And POSI!

i used the painless kit...works a1.....watch your transmission temperature if you do not have lockup,it will run considerably hotter...also you will not get the full benifit increase in gas milage without the lock up[i put a trans temp guage on my 7000r4 conversion] john b

i used the TCI kit in my 76 works great nice and ez to hook up
