Car won't engage Reverse. :o(
I talked about it in the fluids forum but I'm going to post here for more exposure.

My car won't engage in Reverse. It engages in Drive but not Reverse.
Recent history:
I did a full ATF flush using Jime's method.
http://jime.homeip.net/AutoTransFluidChange.html
I used Mobil 1 synthetic ATF which I bought 1.5+ years ago and has been sitting in my garage sealed. It clearly reads "Dexron III" on the back of the package. I believe the front reads "Mercon/Dexron". It's my understanding that Dexron III is equal to our required Nissan Matic-D. So, anyway, I was pleased to see that the package read Dexron III.
Well, it turns out, I was short a few quarts and I had to go and buy some more Mobile 1 synthetic ATF. When purchasing today's Mobil 1, it only reads "Mercon V" on the package. No where does it state it is o.k. for Dexron III. I ended up using 3 quarts. So, it's about a 70/30 split with 70% being the 1.5 year old fluid from the "Dexron III" container.
I also installed a Hayden 403 cooler at the same time.
Within 2 drives (maybe 30-50 miles tops) my car now won't engage reverse!!!!!!!!!
Is it the Mobil 1 in general (but other people, even Jime, have used it successfully)? Is it because I used 1.5 year old Mobil 1 (but it was sealed)? Is it because I added 3 quarts of Mercon V (not compatible with our transmissions?)? Or are the two fluids not compatible with each other? Is it all coincidence and my tranny was ready to go anyway (I do have 100,000 miles and I have been supercharged since 80,000 miles). Ahhhhhhhhhhhhhhhhhh!!!
Is my tranny toast or, if I go back to conventional ATF, will my reverse start engaging???
This blows. I recommend that no one buy/use Mobile 1 ATF. It's not worth it.

the only time i have heard about this happening, letting the car warm up before it goes in reverse, won't go in R right away/delayed, etc, ment a tranny rebuild. don't know about the oil thing though...

I used to have mobil1 ATF in my car. It sounds like you are LOW on fluid, with the car idling, check the fluid level and add some. You can mix synthetic and regular so just buy some cheapo DEX3 fluid and you should be good.

Yeah..... but I am about 3/4 up on the hatched portion of the 'hot' side of the dipstick. And the car worked in reverse a few times before it quite. I don't think I should have to fill it to the top of the hatch portion for the transmission to operate properly. Right?

Well, I made the 'mistake' of telling him to take his time (1. I didn't want him to rush and 2. I have another car). So he still has my car, over a week later. But that's o.k. The good news is I asked him to try to find a VLSD for me. He did! He found a VLSD from a '97 I30t. So I'm stoked about that. Looking forward to the LSD.

I've seen valve bodies go for no good reason on auto trannys when I worked in an Allison shop, it happens man. Sometimes its just wear and tear. Reverse is always the first thing to go, if you had enough fluid in there, it wasn't the mixture that did it. Don't stress it.
