I was so intimidated of transmissions until I watched this video, unbelievable what a good teacher can do for you!

[@MonsterTransmission]

We are happy to help! Check out our other videos on here and our full rebuild series vimeo.com/eatmyshift/vod_pages

Outstanding instructional video. I learned a lot. Enough to decide not to rebuild it myself and happily pay someone for all that work.

[@bowl-of-chicken-soup7107]

I may be about 4 years late but as a teenager trying to disassemble a th350 for my dad, this video is saving my life. I can’t thank you guys enough

[@LandonRoy-cv9rt]

I followed this video step by step and I successfully rebuilt my own TH 350 and it’s amazing, so smooth, thank you I saved at least $1250 and I KNOW I did a perfect job with high quality B&M part kits. THANK YOU MONSTER TRANSMISSION

[@keenaconner2108]

Yeah but he fails to show you exactly where your check balls are. There are 4 and some transmissions have had a shift kit put on them so then there sometimes is only 1 so i have seen in several other videos. Also a few other things he does leave out in this video like alpt of parts have to be lubed back before putting back toether and lip seal tool it takes to lock other parts back in amd soaking your clutches in transmission fluid for a couple hrs before rebuilding.

[@MonsterTransmission]

This is just the Disassembly, all that is covered in the rebuild portion.

[@lfk76]

Perfekt instructions, disassembled my old short TH350 K Thanks from Sweden!

[@joracer1]

This vid is great, but who ever designed that transmission was a genius...

[@gettinthrewlife76]

Thank you, this video is so going to help me when I redo my th350 for my 76 Buick Regal 3.8l. ✌️ out from Modesto,CA 👈😎👉

[@brianortiz2200]

Great video There was too much water on there

[@mikesimek6448]

I could take it apart for sure, but by the time I get to putting it all back together I wouldn’t know what bolts went to what and totally forget how to put it back together, it’s definitely worth paying somebody no matter how you have to raise the cash. IMHO

A tow truck driver towed my company's 1981 Silverado K10 wrong and destroyed the tranny. Yes, we're suing. I spent the winter of 2022-23 IN NORTH DAKOTA ON CRUTCHES. On ice, thru snow above my knees. The tow truck driver's employers were heard to say, "We've gotten away with this before, and besides it's just some Indn's truck". Racist and arrogant and they don't deserve to be in business. This video has been a LOT of help, since I have not rebuilt a TH350 in 3 years. Yes, this Indigenous woman rebuilds vehicles. So thanks, Monster! Btw, the rebuild by a top local transmission shop cost $2,365(.56, including replacing the front u-joint in the drive line). Add in lost income and pain and suffering and we're talking serious money. Not to mention the lack of respect of the opposition for business.

[@mathewshackelford8037]

The amount of water that came out of the transmission is crazy! Great video though!

[@cobaltsslsj5891]

yes car must have been under water

[@jamalcole1985]

Nice video. Gil Alfonso Is rebuilding a th350 for my Caprice.

[@faridbakhshian3373]

What’s the governor’s job in this gearbox bro? Thank you

[@marocky92]

super intrestimg, greets from Germany

[@darylvoorhees2629]

I just finished rebuilding my th350 and have it in the car. The transmission performs well (shifting, etc...) But I have an issue with tranny fluid pushing out the tranny dip stick when I shut the engine off. After diagnosing the problem I blew air into the dip stick to check the that the breather vent isn't blocked in any way. I removed the vent tube and found that the passage way to the breather vent cap doesn't vent. So the tranny is building up pressure and blowing out the fluid through the dip stick tube. I followed all steps when rebuilding and can't figure out what the blocked is caused from. Anyone have any ideas before I pull the tranny from the car and take it apart again. Thanks for your help

[@Stumann6661]

Great video for the "DYI" guy. I would use more specialty tools, i.e. a seal puller tool as well as a front pump removal tool. By the way, what glove are you using? I have tried several types, but haven't found ones I really like. Those seem to fit well without hindering your dexterity.

[@MonsterTransmission]

Thanks! Yes, we try to show how you could do it in case you're missing tools. Curt is wearing Black Nitrile gloves by Safety Director Elite. They are industrial gloves, latex free and powder free.

[@Jorgenson80]

Looks like water/coolant got in there. Replace radiator or secondary coolers.

[@camodudemtbh7594]

How much would you charge to rebuild a transmission like that?

[@MonsterTransmission]

The price will vary depending on the build and application of your custom built transmission. You can find them here: www.monstertransmission.com/Turbo-350-TH350-Transmission_c_3938.html

[@davidclark5138]

Where can I get the rear clutch pack lock in compresser

[@keatonbeckham5214]

can i use a c clamp instead of the compression tool?

[@MonsterTransmission]

This is not the preferred way but it has been done in the past by other builders we always suggest to use the Compression Tool. Thank you for choosing Monster Transmissions!

[@davidclark5138]

Where can I get the froot press

[@MonsterTransmission]

Give us a call we'll help you out 800-708-0087

[@keenaconner2108]

Yeah how to you release the band at 11:50???

[@MonsterTransmission]

You can apply the band through the valve body area and use a large flathead screwdriver to help pull it out.

[@keenaconner2108]

Yes i figured this out.. Was trying to do what's in the case before messing with valve body..but figured out the servo has to come out first so it will release it. Thank you !

[@papanesto1976]

What is wrong with the fluid in this trans. Looks like canola oil!

[@ModsnRods]

It's old. That's why she on build table!!

[@yankeeroad626]

I think they pulled it from the Titanic! Either that or they gave it a pressure wash enema!

[@bobstiles5639]

its not fluid its water. If you look as he's pulling the trans apart theres plenty of rusty parts inside.

[@mrmanitoba]

That small snap ring is almost impossible to remove.

[@MonsterTransmission]

Haha yeah it's a tough one!

[@jimmyers8939]

had some water in it.

[@buchanansleeve7427]

omg that oil is nasty
