700R4 (yeah, i know its off topic)

[Mike Hoenes]

depending on  the year there are a number of mods that need to be done to
the 700r4. if  you have a pre-87 then you need to either get a 10 vane
upgrade kit for your pump or just get a 10 vane pump. if you have a 84 or
earlier, get a newer input shaft - they are beefier. also change the fron &
rear sprags to the new design.
Fairbanks has a billet second gear servo thats worth getting along with the
WOT sleeve. Shift Technologies (same company as Faibanks under different
name) puts out a shift kit that substitutes a number of valve body springs,
etc; and has directions for modding your seperator plates, etc. its
relatively inexpensive at about $35.
i went with a rebuilt corvette converter - 2000 rpm stall.

there are two manuals put out by ATSG for the 700. one is a rebuild manual,
the other is an upgrade manual. buy them both. they are a bargain at $10
apiece. buy some auto trans assembly grease too.

total rebuild cost on my 86 700r4, including the $50 for the core i bought
at the boneyard - $225.

i never rebuilt a tranny before, but it came out perfectly. consider doing
it yourself. if you need a question answered, drop me a note.

I can send it to you after I d/l the latest SouthPark episode.  The manual
ia
almost complete but is done enough for all the mods.  It's about 2 Mb big.
It
has all the places to get all the supplies and the prices you should pay.
You'll save about 300-400 dollars getting the parts yourself.

What did the tranny come out of?  You may need stiffer springs in some areas
if
it wasn't at least a Corvette Tranny.

Talk to you in a bit.  Tell me if you still want the manual and your MB can
handle 2 Mb.
