I have read the datasheet for your Pennzoil Multi Vehicle ATF. Please confirm my understanding... Your Multi-Vehicle ATF is compatible with Shell LA2634 ATF fluid? Any more information would be greatly appreciated.

hmm... not a very detailed response, I'm still not convinced. But you can try it if you want.

I will be trying it out... I have to rebuild my valve body.

As you recall, I changed out the tranny fluid and filter a couple months ago and now have 1,000 miles on the Pennzoil MVATF. Now with the fluid fully integrated into all parts on the transmission, I can give you my impressions of the fluid compatibility.

I first decided to change out the OEM fluid after experiencing an occasional hard second to third shift. At the time, I installed an aftermarket (non-Filtran) filter and some Redline D4 ATF. After about a week with the Redline, I had an occasional slip (hard shift) which went away afterwards. At the time, I had the characteristic whining sound coming from the tranny oil pump which, as we all know now, is attributable to the thinner O-ring that comes with the aftermarket tranny filters.

Then after about 4,000 miles on the Redline D4 ATF, I installed a dealer Filtran tranny filter with the thicker O-ring along with about 8 quarts of Pennzoil Multi-Vehicle ATF. The tranny whining sound was eliminated and the car appeared to have cold morning shifts more similar to the OEM fluid (you could feel them but they were not harsh or anything). The Redline fluid by contrast had a very smooth cold morning shift quality.

After 1,000 miles on the Pennzoil MVATF, I am very satisfied with the overall performance of the fluid and would recommend it to anyone with the 5HP30.
I no longer have any hard shifts like I did with the Redline and OEM fluid but I do have a slight slippage from second to third (like I did with the OEM fluid) which is probably a worn clutch pack that I will need to eventually replace.

ZF's fluid approval charts were updated on the first of this month. No pennzoil in the list. Still only la2634.... and I find no mention of it in any of the current pennzoil product data sheets, only dexron III mercon replacement. I personally don't believe it and wouldn't jepoardize my transmission by using it, if I had a 540 auto that is...
If you look on the zf site there is an area there for manufacturers to submit their product for approval...

IC Bill... I still have time to decide... I will be dropping my valve body next week and will probably be another week before I get it back.
