Homemade transmission pump puller

This tool costs about $20 to make as opposed to this one:

Hope this helps the rest of you poor builders like myself
You hold the nut that is under the top bar still with a wrench and tighten the lag bolt with the vise grips. By pushing down on the input shaft that can't move, the pump stator gets pulled up. Use the pipe clamps(2 in series) to pull up against. Just Tighten the bottom two bolts until they are snug against the stator. You could possibly damage the stator if you make it too tight.
With an air cut off tool, it took about 1/2 hour to set up. Don't forget the little cap nut on the bottom to make it easier to spin in the end of the input shaft.

Good job but mine is even simpler! Just get two 12" long carriage bolts that screw into two already tapped pump holes on the tranny that are threaded for the purpose (5/16" or 3/8", don't remember. May need to even cut new threads on the bolts for those silly metric trannys). Put a couple of pieces of 6" x 1/2" water pipe on them and, voila! - slide hammers. Pops the pump right out.

This is a 2000 model 4L80E. No holes are tapped on this pump. At least on mine there wasn't.
I also do 700s and may try a 350 next month. I'm hoping I can use this same puller on all of them.
What trans has the holes tapped? That's good info and would make a quicker pull than what I did.

Most GM transmission has two tapped holes in the pump.
It's an easy matter to tap two holes in a pump that doesn't already have them.

For many years, I used a simple cheap "dent puller" type slide hammer that can be purchased at most any auto parts store or even Walmart for less than $20.00. The threads on the end where the cap screws on to hold the sheetmetal screws, are usually correct for the threaded holes in the pumps.

I just use a piece of all thread with a nut and my slide hammer handle. It's easy to tap the holes with threads for those that don't already have them.

oil pump puller

Hello bugsdad, superb!

I did the job with two exhauster pipe clamps (40 mm diameter) fixed on the shaft. Then I pulled the pump out with a 3 arm bearing puller. Even a 2 arm puller should work. Easy job, if you ask me.

Regency Red;

I will point a couple of items;

This thread is 2.5 years old.

Bugsdad has not signed on this board since July 2006

Some transmissions have various items bolt into the pump & will foul up the works if the pump is pulled out with out removal of these items. SO the pan must come off first.

IF you are a DIY person with little knowledge of the trans box you are about to work on.... I would pull the pan off first for a look - see.

No idea what a DIY person means. Even I would have less knowledge than supposed, nevertheless I could be right with the procedere descripted above.

The pull off job was dedicated to a 4L80E only. There was no use for open the pan. Other trany may be different of course. I did not stress the fact, should I?

Sorry for the reply to that old thread. I had really no clue that I would enter a minefield.

DIY = do it yourself

I do not know what you mean by minefield.

My post was a general informational post for folks that would pull a pump out without knowing what was connected to it.... my post was not directed at only the 4L80E tranny

IF you are pulling the pump out of a tranny , there is always a need to open the pan.

WHY would you pull a pump out only? There must be a problem to pull the pump out, the pan is the first place to look for metal debris.

Makes no sense to pull the pump only IF the tranny has troubles.

I do not see any person mad.... I pointed out it was an old thread and the original poster has not logged on in a long time . So dont expect a reply from the OE poster.

IF the pump is leaking , I'd pull the pan for at least a filter change.

IF the pump was leaking after a fresh & proper rebuild , then mayb only pull the pump.

As I posted earlier , A DIY person could get into trouble with a different trans that has items bolted into the pump that could break IF the pan is not removed for a look see first

You need to listen to Cros when he is talking about trannys - has been servicing them since dirt was invented. Never confrontational, jsut good sound advice. And he speaks w/ straight tongue - a lot of them do have little goodies that go into the pump from a hole in the case and pulling one by a DIY'r w/o doing some reconnaissance can be disastrous.

To remove the pump, I thread 2 bolts, the tail bolts are the ones that fit, then I use a carpenter's hammer to pull the bolts like if they were nails, works great and cost is zero, I challenge everybody to pull a pump faster.
