I'd replace the whole pump section. The pump is lined with a special anti wear coating, and I've heard once the vanes get messed up, you might as well junk it. It looks like you can pick up a new pump for around $250.
You can replace just the rotor and vanes as long as the surface of the pump isnt scored. Ive had a few pump failures where the rotor broke and I was able to reuse the pump housing each time. Lucky..... Also you may see how much to freshen the trans while it is out. Its cheap for me since I build them.
Not sure yet. I may just get another salvage trans and swop the pump/ parts . I'll dig around a bit. I just figured small Metel shavings in the the torque converter will mess it up to. So idk... Pump is bad and the torque converter could go. But the price for the two of them would cost more then just getting another salvage trans.
Check out this video. You can pick up a rebuild kit off Ebay for a couple hundred dollars and just follow along with the video. It really is simple as long as you follow directions.

I would suggest, like Matt is, that you look strongly at rebuilding it. The rebuild kits are cheap enough and you know you'll be good after it's done. At this point it's already out.
I've been down the path of swapping out motors I've blown with junkyard motors, and sometimes it works out, but sometimes what you replace it with from the junkyard lets go 4 months down the road and you basically end up right back where you started but with a lighter wallet. Unless you take apart the junkyard piece you're just rolling the dice, closing your eyes, and crossing your fingers... Of course if you're going to be taking apart the junkyard piece anyways why not just rebuild what you have... I learned the hard way you're usually better off rebuilding it yourself.

That right there is why my truck ended up with a brand new motor from GM, instead of a reman engine, or a junk yard engine. Like you, i had zero dollars to spend on anything at the time. And i decided the last thing i wanted to do was spend my last couple hundred bucks on a junkyard engine, and it be a POS.

Yes since pump went a close look at the converter is needed. Usually when the pump goes the pump drive on the converter is trashed.
Now yes you can buy a rebuild kit on ebay but I wouldn't recommend it. I would recommend purchasing locally or from a reputable online retailer like transmission parts USA. It would be around the same price and actually have customer service.
Now the 4l60e cannot be rebuilt with basic hand tools.
You need specialty tools such as a compressor, low piston press, heavy oitside snap ring pliers, bushing drivers, T50 star bit, clutch press, inch pound torque wrench and more. Just a heads up.

That is exactly why I have extra transmissions in my garage. I went to the junk yard and picked one up for a few hundred bucks, slapped it in and got about 6 months out of it. I then swapped in the trans from my parts truck and that went real quick. That is what led to my frustration and the decision to rebuild it myself.

I have rebuilt twice now, and am doing a build for another members truck this week. I have managed just fine with hand tools. standard snap ring pliers work for the small rings and a long screwdriver for the big rings. An extra hand to lean on things to compress springs while removing/installing snap rings works well. You can pick up an inch pound torque wrench easily enough, and honestly it should be a standard tool in everyones box anyway.
Watch the video. He makes it very easy to follow along and specifically talks it through using standard garage tools and stays away from the specialty tools.
This is the rebuild kit I have used. I am very happy with the product and the customer service.

Yes you can get by with using most hand tools but the low piston is going to be almost impossible to get out without a press. There is almost no getting around having a bushing driver set. The bushings are so soft you will deform them trying to press them in with a socket. If you dont replace the bushings then youll be going back through the trans very quick. Those are the two that are required and you can make your own tools to get by on the other pistons and such. Atsg manual is also a priceless thing to have.
As it turns out I can get a new pump from Motown automotive for 98 bucks. So the plan is to just buy the new pump and just put the valve that was rebuilt into new one. Still have to wait till next week. The ol girl has Ben down wayyyy to long! Thanks for all your help guys!
I was looking into (and still am) rebuilding my trans. I found a Borg Warner rebuild kit on Amazon for $75 with borg Warner friction clutches and steels. Just a heads up if you want.

the trailblazer is up and running again!!! We did end up rebuilding the pump. All is good runs and drives as it should. So I of course had to take it to the trails! Started putzing around the field and noticed the temp was hot as shit! My damn fan clutch went out so I whipped in an e-fan wich surprisingly enough make the TB run cooler. Temped it in last night and really re mounted it today. I would like I thank you guys for your help and input.
and I have also discovered a lurker by me. He was out with me last night too.
Honestly dude. It's a big ass e-fan from a monster truck I acquired. I really just threw it in there. It's ugly as sin but it works... It's as big as our stock fan. And these no shrowed
I'm not sure how pictures he texted you are going to help the rest of the Forum. Considering the cooling issues our trucks are known to have, all documented success stores are great!
Did you just put a toggle switch in the cab for turning it on and off?
