He's trying to help, he spends a lot of time posting here trying to help, and with all of his experience he's been a huge help to me over the years in owning a 2002. So, I appreciate your response on that topic and I'll leave it be.
Next.
The transmission...Look, I didn't know about the transmission issues either when I bought the two Volvos listed in my signature below. I bought them in 2008, 8 years ago...you think YOU feel bad for buying one of the "bad years"...Hey Man! I bought TWO of them at the same time!!
TWO!!!
Why do you think I wrote up that Valve body piece in the resources section? I was under the gun to repair TWO cars with the SAME problem...and the dealer wanted over $6K to fix the XC when the problem first manifested itself...try selling THAT to your significant other..."Hey honey, those two cars we bought last year? Yeah, uhm, we're going to have to spend $12,000 to keep them on the road"...
I was fortunate in that the Valve Body surgery was successful on the XC, cost me about $700 out of pocket (plus some serious time under the car) and allowed me to do the same on the T5.
From your description, I don't think the transmission problem is electrical in nature...the banging was immediately preceded by the engine revving up, right? You may not have noticed as the pickup was bearing down on you, but I suspect that the engine revved way, way up before Reverse engaged. Drive - Reverse (and vice versa) is known as a "garage shift"...and when the line pressure is low, that garage shift is slow. The more gas you give the engine, the higher it will rev, and the more harsh the engagement of the gear will be. I think that's what happened in your case.
So, what to do? First, replace the fluid. All of it. Ignore the old wive's tale about flushing causing failures. At this point, who cares? Your transmission has already failed. New fluid can make a world of difference.
If that helps, then replace the valve body and cross your fingers...$800 all in.
If it doesn't, then replace the transmission. And hope that the used one is in good shape.
If it were me, and I wanted greater certainty, I would have the valve body in the new/used transmission rebuilt. It's a piece of cake when the transmission isn't in the car. Rebuild it, swap in the trans, have the dealer set the transmission to adapt mode and take the car through the adapt cycle. Again, about $800 for that...because you've already got the transmission...
Cheers,
