Getting ready to change the fluid in my 1994 D1, Any suggestions? Does the exhaust have to be disconnected and lowered? Does the Cross member have to be lowered as well? Does the frame have to be spread to drop the crossbar or are some D1 loose enough for it to drop with a little persuasion? If the frame has to be spread, what tools are required for this?

Hello Troy,
I just did the fluid and filter on my '96 D1. If you're just draining and refilling fluids, you don't have to drop anything. However, if you are going to replace the filter, get ready for some fun. You do have to drop the Cross Member, I beat on it with a hammer and used a very large pipe wrench to persuade it out of there. Some say you don't have to drop exhaust, but I had to. All in all it was around 8 hours work. Oh, if and when you get to the filter, on my '96 I needed quite a large Torx bit to get the filter off, you definitely do not want to strip these bolts. I can't remember for sure, but perhaps it was a T-30, maybe someone else here knows for sure. I will say, next time that process needs to occur my rig will be at the dealership..Good luck.RS

I read a Service Bulletin from LR recently stating that ZF recommends never changing the filter after the first 30k mile filter change, unless you suspect it may have become contaminated. Let me see if I can paste it.

"A/T - Filter Replacement Interval

Section: General Information

Date: 31 October 1997

Model: All

Applicable to: USA/Cda

Subject: Automatic Transmission Filter Replacement Interval

Service Bulletin G97-027 introduces new Maintenance Schedules for the Land Rover product line which simplify the routine maintenance requirements for all models.

We wish to call to your attention to one of the important changes found in these revised schedules:

^ Effective with this Service Bulletin, the requirement for Automatic Transmission filter replacement has been reduced to once over the lifetime of the transmission. The change is to be performed at the 30-thousand mile service.

^ All Land Rover products equipped with the ZF automatic transmission produced since 1987 benefit from this change in policy. Reduced maintenance costs for owners of older Land Rover product is one of the key benefits of this change in policy.


ZF has advised Land Rover that a filter change after the 30-thousand mile service is required only if there is reason to believe the fluid has become contaminated. If you have questions regarding this matter please contact your Product Support Representative."

Anybody disagree? I'm about to do the fluid at 97500+ and wondering if this is the norm. I bought the truck at 69000 so I'm assuming the filter was changed around 30k.

Steve

If it was me I'd change it regardless of what ZF says - If it breaks they get to sella nother transmission

Be careful not to overtighten the drain plug when you re-install it. It is one of those kind with the magnet in the center of a hollow shaft. Since the shaft is hollow, like a straw, it is not very sturdy, and you can easily strip it right off of the plug head. I found out the hard way.

Troy, are you just replacing the fluid or are you doing the filter as well? The fluid is straight forward: drain the old and put new in. Make sure to put the correct amount of fluid into the transmission that came out.

If you are changing the filter, first shift through all of the gears. Then drathen it is a little bit more involved.

Wow, scratch that last part. What I was trying to say was:

If you are changing the filter, then it is a little bit more involved.
