Where are some of the best places to get a transmission. I have been looking into monster transmissions but after a friend's failure and word of other failures I don't think that's a good idea now but I'm in need of a transmission and don't know where to start my search for a performance transmission or maybe I should just go to my local transmission shop for a rebuild of my 4l60e

I vote for local. You should be able to find a shop who does quality work and backs it up

I needed the same trans a few years ago, stock one though. I called every trans shop within 30 mins of me. All were 12 months or 12k miles they did the swap for around $2k. I went with a GM Good Wrench from a local dealer, 3 yrs 36K miles. It was like $1850 with exchange. Put it in myself. Shifted better than the one I had for years.

A GM trans is assembled by a trained tech, what ever doesn't meet spec is replaced. They walk over to a self and get a Gm part.

A standard local shop rebuild is clutch pack, seals, gaskets. If it needs a pump or any other parts that's extra and they use after market parts.

I would guess if you want a performance trans you could spec the parts but it will cost.

Yes I need to be able to handle 600 or 700 hp you think my local shop or gm man are up to the job I'll call around

+1 on the GM transmissions. One of the things that GM does with their rebuilt transmissions. Is if there were any engineering changes since the transmission was originally built those change will be incorporated during the rebuild. And I like the fully transferable 36-month/100,000 mile limited warranty.

with that kind of hp goals, i would go with a 80e the 60 can be built to handle that power, but in the long run the 80 will cost less to build, and last a lot longer..imo

This is what a local builder does to a 4L60E? Does this sound good? Is there anything he is missing?

      Ac not keeping up

      By Grumpy Bear · Posted

      While you are waiting on parts...   On my last few vehicles I've been installing full ceramic UVA/UVB/Infrared blocking window tint even over the solar glass my 2015 was fitted with. At high sun angles on cloudless days this is HUGE reduction in compressor load (interior heat from radiation) and your personal comfort. The new generations of Refrigerant are not as efficient as they once were.    I can't see my breath (meat locker style) but I can run the system on very low settings on very hot days and be quite comfortable. It keeps up well and if you use the recirculation until cooled down, it does so fairly quickly. If ultra humid stay in recirc. The blend door has a minimum; you won't suffocate.

      What a wonderful result! Great story telling to. You are quite multifaceted sir.  I'd keep it. Four is my limit too and yet we have five as well. One assigned the 'salt car' to do all those tasks you hate to ask of your 'Save for Good" crowd. 😉    Don't forget the antifreeze.    The Iron 4.3 is a favorite of mine.

      Ancillary parts to the lower intake and connections went together without issue.   There was a brief pause when I leak-tested the fuel lines and injection system. Fuel was spraying all over. Lovely. O-rings weren't sealing the fuel lines to the spider, and inbound line was leaking at schrader valve, leaks at both flange nuts. It's moments like those when you just want to set fire to the whole shop, and be done with it. I was mostly enjoying the project up until that point, and was tracking to an agenda of having a running Blazer and a cold beverage in hand by dinnertime.    I found some larger Viton o-rings for my spider and some grease to get them to seat. One leak solved. Swapped fuel line Schrader core for old core. Still leaked. Swapped entire valve for old valve. Leak solved. Nudged the flange nuts a little tighter on the connections. Another leak solved. I could cycle the key / prime the pump and the intake was staying dry.    Reassembled the upper intake, with 10,000 vacuum lines, and filled the cooling system with water* (this is temporary, I'm not done with the cooling system yet).   Showtime!!   Cranked it over and smoke billowed, it was running rough. CEL illuminated and began flashing. P0300 and I somehow tripped a code for the TPS sensor, voltage low.    There's nothing as unrewarding as a vehicle that won't run (and produces the same code/problem) after hours of research and work.   Clearly I was in over my head. Was the timing off, did I stab the distributor incorrectly? Is the new distributor bad? With my limited OBD 1.5 data stream I really don't have a lot of parameters to see. The engine was pulling mad timing again (flooding?).   Think, Atlas, think.   1-6-5-4-3-2. One, six, five.....four, three, ....two. Wait a second. That makes no sense. 1 is the forward cylinder on the driver's side, so 2 should be the forward cylinder on the passenger side, not 6.    I can't believe it, but I'm looking right at it. Swapped 2 and 6 on the distributor and turned the key over, and...   It fired, coughed and stumbled, smoked, and then settled into a smooth idle. The scanner showed no codes, no lights on the dash, and the throttle was nice and responsive to gentle revs while it warmed up.   It's working!!! IT'S WORKING!!!   I paused for a late dinner, no cold beverage yet. I was determined to do my shakedown run. Did a basic safety and fluids check one more time and then went out and put almost 70 miles on it last night. She's a runner, runs good.   Came home and did a post-trip, post-mortem. The underside is dry *except* for where the last owner RTV'd the snow out of the intersection of the timing cover and oil pan. He said he had replaced the timing cover seal, but, my dude had clearly done it incorrectly and then tried to hold back fate with black RTV. Never works.   Yesterday morning I replaced the broken driver's door mirror. As much as I hate cheap Chinese parts, thank goodness for cheap Chinese parts. I think an entire new power mirror assembly cost me like $30, and it works perfectly. Replacement tail lights (faded, and one was busted) ran me about $12/side. I have a door pin kit ready to go in because the driver's door sags just a little and I want to fix that because there's nothing sadder than a saggy door.   I don't know what's next for this rig. Half of me wants to take some nice photos (there's a park nearby with a HUGE American Flag that always seems to be catching wind) and throw it up on CL/Marketplace for a couple grand and see if it flies. The other half of me... I've got a sweet running S10 Blazer that's been keeping my mind off of whatever I'm going through right now, and it's bringing some joy, and is cheaper than therapy. Maybe I'll keep it around for a little while. However, this is my 5th vehicle, just for me. 4 is really my limit, but they are not junk, so need very little attention. I don't know...there's a point where it's just too much and I don't see owning this truck long term. But I solved its major problem, got it running, so I'm going to stick a feather in my cap for now.   Sometimes we just need to get our hands dirty and fix something in the physical world to gain some satisfaction.
