The trans in question is a T-19? they weight around 150lbs.
You want a good trans jack with a good foot print.
I have this one, and used it putting in a Mercedes trans.
It worked ok but the strap across the top was a P I T A to tighten down. When I bought it, it was $80.

I picked up this one off CL, guy used it one time and just wanted it gone, think I paid $80 for it.
Used it one time to drop my T-19, and worked great, has a larger foot print, and easier to use.

If you are taking the trans out to take to a shop, you will have to have the truck high enough to roll out from under the vehicle.
I have 4 of the 16" Ford factory white steel rims,
then place a 14" Mercedes steel rim on top of it, and use this to elevate the truck.
The 14" rim locks right into the 16" rim and there is no slippage or movement, makes it very stable.
Think I also raised the rear the same way.
Make sure the the ground you are working on is solid, and firm.
Preferably concrete. You want something smooth to roll the jack on. Just be safe.
Not really that big a deal, just unbolting a bunch of junk,
and trying to remember how it goes back together.
A 2 Post Lift would be the best thing to have...Just saying...
