[@joshuachambers8989]

Best in depth video I've seen. Includes all necessary steps and no irrelevant steps.

Q lŕ

I’m doing a 4x4 swap on an 87 Squarebody and this video showed me everything I up close. I’m going to drop my th400 Change the output shaft and add the np208 with the proper transmission crossmember. Very helpful - thank you!

[@kevinrichards3288]

91 was the last year for those square body Blazers, & same with the square body Suburbans & square body crew cab pickups too. Just the half ton & three quarter ton regular cab square body pickups stopped being produced in 87 but the one ton regular cab square bodies on the other hand stayed in production up through 89.

I'm getting ready to do this on my 85 3/4 suburban as part of an NV4500 swap. I think this video is going to be very helpful when I get around to it. Thanks for listing all the steps and the basic order of operation. Looking forward to more videos with the CUCV.

[@sierraayers2767]

The crossmember for your transfer case has spacers. You had them below and that will cause a vibration

[@garymcnemar6620]

Thank you! I'm gonna be installing my rebuilt 400 transmission into my 1983 Titan Champion RV, with a 454 motor. I didn't remove it, so this video, will hopefully make it easier?

[@Allaneta]

Great job bud. I enjoy finally having videos on my m1009.

[@OdysseyOverland4x4]

Thanks! Much more to come! Share this video! Cheers!

[@combatbeard7643]

I have an m1008, 84/85. I see plenty of videos of people wheeling, but 0 on repairs.

[@Carla-tz7qw]

My dad put a Clark 5 speed transmission behind a 453 Detroit it was I think a 77 banaza,one ton. Everybody ask why it could pull anything and outrun them. He had a two speed rear-end.

[@tomfitzmaurice3703]

Great video....just what I was looking for

[@ryanstamper8107]

How do you fix a transmission that doesn't want to shift in to any gear that is on a 84 custom deluxe k10 automatic

[@greglopez2217]

Did you fix it? Mine started doing it too 😂

[@jeffrentsch4318]

If the wrench/socket fit perfectly it is the correct one.

[@chickenfoundation9323]

I think he means it being the original size

[@Papikevnc]

Did you install that double cardan joint on the rear driveshaft because of the angle? I’m thinking of adding mine for this reason and also did you put that spacers on the transfer case mount back under? I saw someone else in the comments pointed that out thanks man

[@geraldfleshman7267]

Where does the wiring harness to starter attach it is a tube

[@titusmaldonado2556]

So I need to change flex plate on my 83 k5 do I need to take transmission out completely for that? Should I follow same steps as video..and 1-10 how hard is this for a parts changer not a mechanic

[@user-uj3zk2cx8t]

Yes the flex plate is not accessible without removing the transmission...

[@thehomeboy8599]

Torque specks on the bolts?

[@combatbeard7643]

Thanks for the how to video, is your system still a 24v or habe you converted?

[@OdysseyOverland4x4]

Still 24V!

[@combatbeard7643]

@@OdysseyOverland4x4 have you had any overheating issues with the generators?

[@OdysseyOverland4x4]

@@combatbeard7643 Not at all!

[@casdigital5182]

Your engine didnt drop a bit? You’re supposed to support the enginr with a jack stand and a piece of wood or something. Not doing can mess up the distributor and put unnecessary strain on the exhaust to hold up the engine.. anyway, thanks for the vid

[@OdysseyOverland4x4]

Did not have any problems. This is a 1985 M1009 CUCV, so it has a 6.2L diesel. Needless to say there is no distributor, and depending on your engine and trans configuration, I think the exhaust has a few ways it can be routed. This is my take on removing a transmission with what I had available, and with my truck's configuration.

[@mattwoody1089]

Hey what engine do you in front of the th 400 I noticed you have 6 bolts on your torque converter matt

[@OdysseyOverland4x4]

Matt Woody I have a 6.2 Diesel. How many are there supposed to be?

[@mattwoody1089]

thanks for the reply most of the gm small blocks use a 3 bolt torque converter matt

[@shakinglegforballs1067]

Gettr Done ✔ 🙌

[@tonisoza9391]

Is this the same method that work for me on my 1972 K5?

[@Rider-lh2gz]

Toni Soza yes it should if it’s an automatic

[@thatguy_jose]

To bad you didn't show the removal process

[@MuscleCarMike]

Will this video work on a 86 suburban?

[@OdysseyOverland4x4]

Mike Hines Outdoors sure will!

[@MuscleCarMike]

Thanks for the great video, i have to replace mine and im pretty nervous to do it , will turning the motor with the breaker bar throw off my timing?

[@OdysseyOverland4x4]

Mike Hines Outdoors absolutely not! Nothing to worry about!

[@weesebowski8651]

Restoring my 86 k10 and I'm having an issue maybe you could help me with...? 86 k10 4x4 305 standard with granny shift. I pulled a 79 Scottsdale 4x4 350 but was an automatic. Dilemma- I'm having an issue trying to initiate the fit it's about 1/2" maybe less to fit into the transmission! My guess is the metal pin (bushing) that fits inside the engine needs to be removed or changed? Any ideas anyone? I've put my truck off for well over a year to work and how I habe the time I'll be working on this through the winter months! Visit my channel to see the video of the truck....

[@OdysseyOverland4x4]

Not too sure there... When you say 1/2" less, what are you referring to exactly?

[@combatbeard7643]

You might be having an issue with lining up of the pins that act as a guide I am assuming? You might need a different bell housing, for the auto, did you change your flywheel over to a flexplate? Not trying to insult, just sometimes people forget.
