What type of transmission fluid should I be using in a 86 xj6?

Also, I sometimes hear a honking sound when I turn a corner and accelerate. Sounds like something slipping in the transmission. Anyone know what this could be?

 

It should be Dexron III but new Mobil 1 are also good.

 

The original specification was Type "G" but that's been obsolete for ages, being replaced by Type "F" or Type "FA".

If you want a slighty softer shift ....might not be a good thing on an old trans.....use Dexron III. Otherwise use the F or FA.

Not sure about the noise. Hvae a good look at the transmission mounts though.

This may seem ridiculous, but where do you add transmission fluid?? I see the dipstick for the transmission, but don't see a provision for adding fluid.
86 XJ6.

 

The dipstick tube is also the filler tube :-)

LOL! Love it! I learn something new every day.
So I checked my transmission fluid. It was 1/2 qt low. I sometimes have smokey exhaust, and the transmission is a little jerky on upshift or downshift. The Haynes manual talks about a ruptured Vacuum control unit diaphram being the cause of these symptoms. Would anyone know where this unit is located and whats involved in repairing this??

 

No vacuum modulator on your '86 XJ6 Ser III.

What color is the smoke?

PS-gotta be careful using the Haynes manuals...they're tend to cover so many models years and models in one book that the info is confusing :-)

 

Thanks Doug!

Your right! The Haynes manual is really confusing and often misleading. I appreciate your insight and experience.

The smoke is just normal grey smoke, and only for a second when the engine is first started. I changed the plugs last weekend and they all looked perfect with just a little tan coating on each.

I added transmission fluid. It was 1/2 qt low. I have not heard that noise since adding fluid.

 

How many liters of the transmission fluid required the series 3 gearbox?
