Full syn trans fluid

[losh1971]

Need some trans fluid and have two or three options, Nulon, Penrite and hopefully Castrol. I am leaning towards Nulon even though Penrite is cheaper by 5 bucks. I heard Penrite full syn can cause problems. Don't want DX 3 i want full syn or i would just by the best special.

The Nulon full syn runs sweet in the 4 speed VE Box. It's the Penrite LV that causes problems for me
The FS seems ok but Nulon runs the best!

I grabbed Nulon, thinking if it wasn't a good choice i can swap it. Only had two options in full syn. Out of three main stores the only full syns available were Penrite and Nulon.

Something i noticed was Nulon said on the bottle ok with DX VI. Penrite was only DX3.

Strange how this Full Synthetic label has gotten everyone in. There's no such thing in everyday oil as Full Synthetic, it's all based on Mineral Oil and is a load of BS.

Do some research and if you read between the lines you'll find out that all the oil companies are spinning us with crap regarding synthetics.

Back on topic, what was ever wrong with normal Castrol Dexron 3 in these average GM transmissions that we all have ?

My old trans tech uses syn trans fluid. It lasts longer than the old DX3. I use it because he uses it. This trans bloke is the best in the state so i trust him to know his stuff.

My 4L60E has done 428000km. Seem's pretty hard to kill the things.
Here's some academic from Nigeria who's probably using cooking oil in a tranny:

Yes. I run the Nulon full syn in my power steering. It's the quietest VE steering you ever didn't hear Yes I'm being serious!
