700r4 bushings

...not trying to sound ignorant but I think it'd be ignorant not to ask. When rebuilding a 700r4, is it "mandatory" to replace the bushings? If so which ones, all or just certain ones. I'm asking because I dont have a press or the bushing install tools. Thanks in advance

Lets put it this way; if that $3 bushing fails and you have to remove that sucker and tear into it again; you're gonna rethink this.

That being said; there's a lot of 'quality' issues with rebuilder bushings (this is coming from a transmission design aspect). A lot of the bushings the factory built the assembly with are ream-in-place and the rebuilder bushing is a standard size, which may be on the loose side.

Thats just engineer speak.
The crux is this; take your housing to the local trans shop and ask them nicely when they're not busy if they'll press them in for you. Offer up a pizza or whatever. I didn't have a press at home for years and I figure Ive spent the same amount of money on pizza and beer as a HF press costs; BUT its nice to be friendly with the local shop. Don't forget to grab a handful of his business cards. Remember his time really IS money. If you go there a lot; you really should pay his labor fee. Some guys won't do anything without billing you an hourly rate; don't get mad. I have one friend who loves the pizza and beer routine; and another that will charge an hour labor to do anything related to his business during business hours. They're both right.

Bushing press???? I have bushing drivers. Nothing more then solid steel stock turned to fit the ID of the bushing and just a little undersize of the OD and drilled and tapped for a driver handle. I made all mine years ago on a lathe for less then $30. I've used them to rebuild turbo 400,350,powerglides, and 700r. I always replace the bushings on a rebuild. If your worried about bushing clearance, then get a factory service manual out and measure the clearance. Thats how they taught me at Tech school years ago.

I used a 1/2 in. bolt with enough threads on it to push the bushing into what ever I needed it to.I think it was a 6 in. bolt.Then I used a lot of difference sized 1/2 in. washers,thick ones,thin ones,wide & narrow.Some of the washers worked perfect,others I traced around the bushing onto the washer an used my bench grinder to grind it to size,slightly smaller than the o.d. of the bushing.I also had some thick 1 in. plastic and used difference sized hole saws,what ever was close to the i.d.of of the bushing and used those on the under side of the bushing to keep the bushing from cocking when driving them in.This works well but took along time to do.It best to get every thing to size before because you can use them to drive them out.Pay attention to how far the bushing are inside to what ever it is your driving out of so the new bushing can go in the same place.Spray every thing with break cleaner then use red lock tite on the bushing an install. You'll need a big vice to put the bolt head in then start stacking an lining every thing up.I didn't have a press either and I didn't want to pay like 400.00 for the bushing driver set.Auto Zone doesn't have anything that will work.
