So I got my z31T last year and the transmission seemed ok when I purchased the car, handled boost just fine and I was able to drive it all the way home about 15 miles...drove it around for a few days and slowly the transmission started to show signs of an issue, like slippage and rough shifting.

this website http://lucasoil.hodgsoncorp.com/slip...ansmission.htm Says their product will stop those issues. Anyone else try something like this?

I would first check to see if your low on ATF. Or if its burnt or out of color. If its bad go change the fluid then see if it still slips.

fdc_guy

Well the fluid is good, it doesnt look burnt or anything, just slips into neutral under boost alot and sometimes will stick on first or second and won't upshift under boost

I don't think you're going to find an absolute "it's good" or "it's crap" answer. I did a quick google search & found mixed reviews:

Thick fluids aren't good for auto transmissions, but if it's toast anyway, it can't hurt to give it a try.

General consensus has been that it works to resolve the issues I was having before I stopped driving the z...So im gonna give it a try and see what happens.

About 5 years ago I was at Miles Unlimited Z on Beck Street talking to Monty. He mentioned something that he put in his Ford Taurus & the tranny went from "no shifting" to "drives like it's brand new". I just can't remember what it was......

fdc_guy

Lol, others have told me that they put this in a transmission that was on its last leg with like 200k miles on it and it make it shift normal, not slip and basically made it like a new tranny.

Monty I am sure has put just about everything in some of his cars, he is an awesome Z enthusiast, but sometimes he is wayyyyyyy out there high on somethin

I always thought "Lucas" was a British word used to describe their electrical systems. In English, it means "leaks smoke".

Thanks for the random fact!

Probably Sulphur, that is what was used on dynaflows in the 50's.

I put the Seafoam Trans Tune into my Chevy truck and it helped a lot! till I realized I overfilled it XD

Must have been Hundred dollar bills. A worn out trans is still a worn out trans no matter what fluid you put in it. Z31 E4N71B auto trans is not a reliable transmission for the kind of driving most of us do. Do a manual swap before you consider a rebuild. ($1200 to 1600 for a rebuild)
