91 Accord Transmission Problem
 

First of all I have a '91 Accord LX (Automatic), and this is what's going on.

I first noticed something was up this morning on the way to work. As I was driving down the highway at about 70 MPH, I noticed the RPMs jumped from about 3k to 4k out of nowhere, at the time I didn't think too much of it. I didn't touch the car again until I was about to go home, at which point I started it up and quickly realized I could not get the thing out of Park, and the (S)port shift light was flickering. I proceeded to shut off the engine so I could try the Shift Lock, I put the thing in Neutral and restarted the car. At this point I was able to shift into any gear, but once I went back to Park it was locked there again. Just wanting to get home, I used the shift lock again, and proceeded to try and drive off in the (D4) gear as normal. Right away I noticed significant hesitation until I got to about 30 MPH, other than that the car was running fine. From then on out everytime I had to stop I put the car in (2)nd gear to take off, and went back to Drive (D4) after 30 MPH just to get it home. This seemed to work fine, no hesitation in (2)nd at all.

Any idea what's going on? I don't know anything about transmissions, other than they usually cost an arm and a leg to repair, any help would be greatly appreciated.

After taking my car to a transmission shop, it appears the problem lies with my Transmission Control Module/Unit. They wanted to charge me $625.00 to replace it, but I know I can do that myself, I just need to find the part.

So far I'm not having very much luck, the part I need is 28100-PXO-823-M1, anyone know where I might be able to pick one up? The dealer wants like $1100.00, I've seen some on eBay for sub $100.00, but not the correct part numbers. [:@]
