Default 93 Auto trans reinstall advice

Thanks, got some good advice on removing my 93 auto came right out , had to remove one side header (Long tubes) that was about as much work as the trans removal, I used my jack, and a plywood gravity was my friend but going back going to buy one of those trans jack adapters deals looks like all I will need one time deal (I hope) Ok any advice on the reinstall .Thanks

To make a bit of a joke about it, almost every repair manual always just says "replacement is the reverse of removal" or something to that effect. Not terrible advice actually. If you have someone who can help you by adding extra hands, then it may be easier.

If you can rent/arrange to borrow an actual transmission jack I believe it would be to your advantage. You might want to make note of the transmission information on the 'pan rail'.

Be sure the torque converter is fully seated onto the trans snout. The final dimension is about 1/2" between the converter and the pump mounting bolt heads.
You might want to be sure the new converter indexes into the crank snout, although I've only encountered a problem here once in many, many, installations.
When the trans is in place, check that the converter still turns freely. As long as it does, it hasn't slipped forward.
Check that you aren't pinching any wires between the engine and trans.
Don't draw the trans to the engine with the bolts. Get a couple of the lowers started, and you should be able to push it onto the dowel pins and flush. Then tighten them.

There's some little things to watch for. You'll get it.
Thanks all the info all the info it all adds up not a auto guy stick guy but not like some don't know it all yep been working on these old vettes for years. the converter will come installed will do all I can to keep it there .. The dipstick yep crazzy Thanks .. I could not pass this auto C-4 up it was taken apart and painted very quality paint job worth more that I gave for it all new insides and on and on $7,500 so I got a auto lasted 3 years .. 140,000 miles Thanks

More than once I had the trans bolted up and realized that I didn't insert the dip stick tube. It's a lot easier doing it when the tranny is not yet in place.

This thing was expensive (even at Harbor Freight) but it's worth every penny. I can't express how much easier it makes putting a transmission in when you have ***** the will adjust the angle of the trans in any direction. I just wish it went a little higher.

Good deal my trans made it 140,000, taking out not too bad going back a trans jack will be your friend for sure. I had to remove the bracket on my filler tube just would not go in maybe halfway other than that the reinstall was not too bad. Good luck with it.
