1999 Explorer gearbox help

[99exploreruk]

The 1 hour job took 1 day! Had to remove driveshaft to drop the pan. No nasty looking gremlins in pan either. Going to re-torque the VB bolts tonight and fill tomorrow!

Thanks for your help guys!

Good work for that messy job. ATF is good for your skin LOL. That fluid is expensive these days too, you like to do it every few years, but it can cost $100-$200 depending on your brand choice etc.

iirc you need mercon v.
Comma do a multivehicle trans fluid that is mercon v, is what i used

Boys! It worked! I tightened the appropriate VB bolts to 14NM they all took maybe a 1/4 turn. It shifts well now and kickdown is back with no stuttering.

I used a gulf fully synthetic ATF approved for Ford Mercon V from Opie Oils. It took 4 litres to underfill - 5 to overfill and I drained 1/2 L from the trans cooler lines in bits to get it right.

I’m going to start a new thread with the rest of the build so other people can use it as reference now.

As an addition to this thread - removing the front driveshaft is essential to getting the pan drop done. For uk guys go underneath the passenger side and soak the 4x T25 torq in WD40 overnight. Remove the bolts and pull the shaft backwards to remove and tick out of the way. THEN proceed to loosen the pan bolts and drain fluid slowly from one end.

You can drain an overfilled system via the trans cooler.

Pan drop, pan and magnet clean, VB bolts tightened to 14NM, fresh fluid and filter have solved the issues stated at start of thread.

Thanky you all the guys who helped me out throughout this SOS thread - your amazing

Also - go for the rubber pan gasket not new OEM/motorcraft cork!

Cool. If you get chance, you should take pictures as you go and then do a write up on here to show other people what you've done.

Hey Si,

I read you’re jacking up your truck again - would this mean your 3” summit kit will be coming out (and be for sale) by any chance?

Hope your sound

Mark
