Tranny Problems

[caine217]

Well, out here in North Jersey we got hit with some snow.
While trying to take my wife's 93 XLT out the driveway. I blew the tranny (I think). Her 4x4 is out so, I was forced to use the "rocking" technique to get out. During the course of this her reverse went out. A few weeks prior to today, I noticed that it would take a few seconds more than it should for reverse to engage.
Now I can put the car in drive but it's slipping bad and reverse won't work at all. The truck has about 120k on it. I'm thinking about just dropping a tranny in there. I dropped one in my 91 sport that ran me about 2300 but my truck in is a standard shift. From what I understand the automatic tranny should be less. I have a mechanic that can put the tranny in for cheap but I'm trying to determine if it is the tranny first. It most likely is. Also I don't have much money to spend on the replacement so it's will probably a junkyard deal or www.phoenixhardparts.com looks pretty good.
Any suggestions/advice?
Thanks

You could try this

If you didn't snap the reverse band. The easiest thing to try is the replacement of the of the low/reverse servo O-rings. These are always bad to some degree and you will probably see an improvement. This is no more difficult than replacing the transmission filter. New filter, fluid, gasket and seals would run about $50. The procedure is located on page 2 of this thread is located at:

The title of the post is "Low/Reverse Servo Improvement." I would also tighten the valve body bolts when the filter is off. I have found these loose sometimes. Not too tight. Spec is in this post. If that doesn't work, it will need a teardown
