So I hope this doesn't cause a shi*storm and I'll preface this with

*Do you own research on the subject.
*Your car/your risk

So whats the tip?

Ford Mercon SP has been independently tested and proven to be equivalent in makeup to ZFlifeguard6.

Why would you care?
Mercon SP is around $5 a liter/quart vs $30+
Its available locally, globally, and did I mention its cheap.


"I'm not cheap why would I consider this crap?"

Want to flush your transmission? You can buy the Mercon sp fluid run it for 100 miles drain/fill(With ZFlifeguard6 if you desire).

My opinion is you'd spend better money running Mercon SP with a metal pan/filter. You can buy the filter for under $15 and change more frequently.

I've been running it for about 1,000 miles and plan on doing the Metal pan mod, drain whats in there now(mercon), refill with mercon, and drain/fill in 20k miles or whenever I feel like it down the road.

Mercon SP was developed for ford 6 speed ZF transmissions FWIW.

Where did you source the metal pan? Did you need shorter bolts?

 

I used mercon sp in my previous lr3 with no issues. I'll probably use it in this one too.
