700R4 and NP208 Removal

[Waylon]

I’m going to have to pull my transmission out of my 85 K15 to replace a leaking seal and/o-ring. Do you guys separate the transmission from the transfer case and pull them separately?

I plan to buy a transmission jack from Harbor Freight to do the job. I’ve always just used a floor jack but I think this would be a good time to spend a little money to make things easier.

208 is aluminum and fairly light. I would just pull the transfer off, then the trans out... especially if doing it without a lift and on the ground. I did a 6L80E rebuild on my wifes 2011 Suburban and that's how I did it. It will be harder to balance and handle with the transfer attached and you don't have to disconnect much more to get the transfer off first.

Separately.

Yep, separately. It's not hard to remove the 208 and give yourself more working room and less weight to balance on the jack.

Will do!
Thanks for input guys!

Separate, for sure unless you have 28 inch pythons and can bench press about 350 pounds.

I wouldn’t use harbor freight’s red scissor lift trans jack.I used on a Muncie 4 speed at 170lbs and it took all it had.Says it’s rated at 350,bit IDK.

Be careful

Yeah that thing is complete garbage and plus when you put your transmission on it you can't even get it out from underneath a stock height Jimmy. I swore after that I would never bench press the trans into place again. I was already planning to get a Hayden style aluminum transmission pan on my 4l60E, so I'm just taking stamped steel one pan off and I am going to drill a hole in it big enough to fit on the big screw that holds the cup on my jack and then screw the pan onto the jack and then slide it under, line it up and put about half the bolts back in, and then loosen the transmission and drop it with the jack. it's not as perfect as a real jack transmission but I'm hoping to only mess with it a couple more times during mock up and none of those times need it to have fluid in it until the final time (unless I blow it up after final install, lol) but at that point the Hayden pan has a drain plug in it so I can drain it normally and swap back to my installation pan.
