Transmission install

For the first time I can’t seem to find anything on my go to resource for “DIY” YouTube university.

Anyone ever ever take on a transmission replacement job? what’s the difficulty level on this for a DIY guy. Jobs I’ve done so far were relatively easy. basic maintenance, radiator, alternator, thermostat, suspension, leveling kit. I imagine a transmission replacement is on another level. Any advice or insights welcomed. Thanks in advanced!

 

You will need a jack with a transmission adapter, maybe extra jacks to hold the driveline out of the way Auto trans are super heavy. Impact, swivel head sockets, extensions. Mirrors to look at the top of the transmission and see what needs to be removed. The torque convertor bolts are a b to remove on fwd. You'll have to undo the starter. Don't forget to drain it.

 

You can rent transmission jack. Is yours 4x4?

The stuff that gets people is not greasing the front seal on torque converter and not seating the torque converter properly before stabbing it back in the truck.

If the trans is up in place, that TC must spin freely as the bell housing meets the engine. If it doesn't and it's pulled together using bolts, you trash your new trans breaking components!!!!

Grease the TC and the seals inner lips good. Add 2 qts of fluid to the TC, and spin the TC while holding the pilot stub at the end and lift and shake the TC a small amount until it clunks in 1, 2, 3 times... Align the 3 segments ensuring they drop into place.

Now make sure it doesn't slide out while getting the trans up into place.

There are plenty of YT videos of transmissions being pulled. It's not to different.

Last thing, make sure you have the jacks position correct regarding the CG before lowering it.

And you can remove the transfer case first but it's more work than its worth!
