Tranny Tech buddy in Germany looked at the paper and says it IS compatible.
The Redline D4 ATF has been in the since October 2003 and actually removed the slippage I was experiencing between first and second gear. The
shifts are now very smooth and the car is working great. I came across that German pdf file Tiger posted before along with other people indicating it was compatible. If someone wants to pay more for something, that's fine its just if the material (not brand) is the same or better why pay more? I just went to Sam's Club last night and picked up a 156 piece mechanics toolset with Chromium-Vanadium polished sockets and 5 degree ratchets for $60 while other places sell the same kind of set with a name brand for hundreds more. Anyways, I'll keep everyone posted on a monthly basis letting them know how the tranny is behaving but if its anything like the last four months, everything should be kosher.

That is what I thought... Now only if I could figure out a way to sell those $3 fluids for $18... hehehehe... Thanks for your help... now I will use Quaker State.

In your automatic transmission I would recommend the Red Line D4ATF, it is completely compatible with the Shell LA2634 fluid and will mix without a problem. The D4ATF is similar both in viscosity and overall characteristics.

Do you know what's the recommended service interval for the Red Line D4ATF?

Don't know but I would change it every 3 years. By the time you get to three years... most tranny will start to act funny... that is regular stuff and this is synthetic. I will be converting mine to Quaker State Multi Vehicle synthetic fluid. Cheaper and still full synthetic. The key is the filter longevity... how much sediment it can trap.
I got original Nikasil engine too.
