Gone through 3 4l60e on my SAS Jimmy and just over them completely. Started to put together parts to swap to 5speed.
Just picked up from a local salvage yard a 5speed and np231c from a 1993 chevy s10 with all the levers and shifters. Found a 89 pedal setup online. Have a new clutch master and slave. Flywheel and clutch plate bolts. I just picked up the transmission today so I'm trying to look up the casting numbers if anyone can help with that. I then can order the correct clutch and flywheel and front seal retainer and seal and fork...ect. figured I would make a thread for anyone wondering about what it takes. Any help is appreciated.

I wouldn't expect a t-5 or hm290 to live any longer than a 4l60e

Can't you shove a slightly tougher p.o.s. like a NV3500 in there?it's a 4.3?.... ..........
And if it's a 4.3 ...can't you shove a nv4500 in? You'll just have a short ass driveshaft. And not that short either ..you got what? 14" lift under there?

This is a nv3500/hm290. I don't have a understanding for rebuilding automatic transmissions. If this manual transmission takes a shit I can rebuild it myself.

Yes right around 14" lift. Tom woods driveshafts that im already planning to take to a local shop to have shortened or extended depending on what it's going to need.

This isn't a rock crawler yall. This Is a dirt trail / mud / water crossing rig, no need for 3/4 - 1ton stuff. I live in Florida. It's on 31.50s now and will see a max of 35s. It is a new 4.3L. No need to over build it more than it already is. If you want details on the build it's on s10 fourm.

Lol sorry. To many people think you need to build everything to the absolute max to have fun. It's absolutely not true. Stuff will always break no matter what you build. Just know your limits for your particular setup. I know for the trail cruises and mud and water I get into the transmission will do just fine. People act like everything is a toothpick unless it's a completely built 100k rig. Have fun with what you got. If something breaks, fix it. And you know your limits.

Your blazer needs a 35” tire. I have them on my jeepster that’s on a ds blazer chassis. Half ton axles, low power and they’re living just fine. 35’s are a pretty decent size that can do just about anything. I have them on my 4runner as well. I should probably stick with them but have room and cut fenders so I’ll prob go to 37’s. I like you blazer cause it’s not the norm.

Tons of blazers around here. None like that. There was one monster pile on 2.5 tons axles and 46s for a while...haven't seen it in two years.
Our yard sells lots of stock front diffs and suspension parts. But guys Usually only go has far as a torsion twist and boosters in the front and match the rear. That's has far as they get built. Same with Sploders. Nobody "builds" them. Rangers either. Other than a 6 inch Duff kit and 33s. One guy has a linked ranger. He used a d30 CV axle from a 2003 Grand 😐🤔 he blocks trails often.
Mines always the only full width on 3/4 or tons.
I always build, never buy. I just gotta stop rilli g my shit over and totalling it BEFORE I build a cage 🤣

I was approved at Mavis tire for 1500. I'm going 35s but I want the oem rear tire carrier and a set of 16x10 wheels first. Then I'll throw the difference of cash on top for 5 35s. She needs the transmission work done before all that...

I'm picking at the pedal assembly. You do not have to remove the entire dash. Just the keen panel, column and cluster. The only part that got me was there is 1 10mm bolt directly back behind the cluster where the cluster wiring harness plug mounts, remove it and you will see the top of the 10mm you can look on the bracket underneath and you will see the threads coming through the bracket. Disconnect the brake boost and rod. 1 10mm bolt to the dash under a/c controls. Unplug everything in the way... took about 45min to get it out. Im getting in the pool now and I'll stuff the manual assembly in there and mark my holes to drill.

The clutch master and slave I ordered was wrong, so I shipped that back to rockauto and already have the correct one coming. That's why I haven't drilled the holes in the firewall yet. Some say the bolts are 3/8ths and the piston housing is 1 1/4" but I rather wait for the part to come and measure it myself before I drill. So next weekend is going to be busy working on it. Parts have been trickling in. Today I received the front bearing/seal retainer and front seal and pivot ball. It all went together nicely. For anyone replacing the pivot ball I just used a gas torch and got it hot as heck and got some vice grips in there and twisted and pulled for 10min and got it out. The flywheel and clutch showed up along with the ARP pressure plate bolts and flywheel bolts. Waiting on the OE GM clutch fork and OE GM throw out bearing to arrive and then this transmission should be ready to go in. I did notice in the shifter assembly I am missing a square bushing to keep slop out of the stick. I couldn't find a s10 shifter or that bushing so I ordered a shifter for a full size truck and am robbing its guts to rebuild the s10 shifter. That's all the updates for now... here's the pictures.

Alright so I had the wrong front seal / bearing retainer that the throw out bearing rides on. I got the correct one in the mail today. And I couldn't find rebuild parts for a s10 shifter assembly. So I bought one for a full size truck and just so everyone knows all the parts are the same besides the actual stick and housing. I was able to use all the parts and my shifter is like new. Not bad for 85bucks. I also got the correct clutch master and slave cylinder. So I can now drill the holes in the firewall and put everything back inside. My buddy found a first gen bervarda and snagged me the back seat and armrests and driver window switches for 100 bucks. He's going back to check the condition of the tire carrier for me. Tomorrow im putting the dash back together after mounting the clutch slave and then pulling the transfer case to get my JB SYE out of the 233c to put in the 231c.
