What is a good substitute for type a trans fluid the manual calls for since type a is nearly impossible to find around here.

I had a newer version and its manual said "type F and nothing but"      Type A, you Will not find unless you get lucky at an old farm sale or something similar... Dexron (and each roman numeral, I think they are up to VI,=6, now)    each rendition is directly compatible with the previous versions...   Type A /Dexron  and type F are different, type F has different friction modifiers....

 

strangely type F is readily available even though the last car built,  that "required" Type F was about a 1977-78 model!

There are lots of theories out there, but this sums put the more reliable thoughts I read.

Transmission Fluid Information

Written by Daniel Stern

Submitted to the MML: February 9, 1995
--------------------------------------------------------------------------

Good morning everyone.

Here is the lowdown on transmission fluids:

Automatic Drive Fluid. Used on REALLY REALLY REALLY early automatic drives.
Automatic Transmission Fluid, Type A: Used for a few years in the '50s
by everyone until:
Automatic Transmission Fluid, Type-A/Suffix-A. This
stuff is also called AQ-ATF. Specified for Torqueflites until:
DEXRON came on the scene in the late '60s. Dexron was the specified
fluid for Torqueflites until:
DEXRON II replaced Dexron in the 70s. There were some early-90s variants
of Dexron II called Dexron II-D and Dexron II-E. Dexron II was specced for
Torqueflites until VERY recently, when:
DEXRON III shipped in place of Dexron II. Dexron III fluid also meets
"MERCON" specs for Furds. Dexron III is specced for new Torqueflites,
but not for some of the new FWD MoPars, notably the Neon, which call for
ChryCo Spec 7176 fluid.

NOTE: Type "F" Fluid replaced Type "A" as the recommended fluid in
Ford's automatic transmissions, instead of Dexron. "racer myth"
abounds as to use of type "F" in a Dexron transmission to get firm
shifts. But I'm not about to try this on an expensive Torqueflite
transmission which shifts beautifully on new Dexron III. I cannot
recommend this procedure. Stick with what Chrysler says here.

There was also a Type "JD" fluid in the '70s for Furds with "Jatco"
automatic transmissions, but I believe this too has been superseded by
Dexron II and III.

HERE'S THE IMPORTANT PART:

The A/AQ-ATF/Dexron fluids are BACKWARDS-COMPATIBLE. That means that all
transmissions that called for Type-A, AQ-ATF, Dexron, Dexron II, Dexron
II-d, Dexron II-e, or Dexron III should now be using Dexron III. >

Alan, gues that guy didn't like "Furds"  haha

 

That was in 1995, he hadn't gotten to the Chrysler Mopar 4 fluid that you have to use at like $7-10 a quart :wallbanging:

Way off topic but...

Daniel Stern is a Mopar fan and an authority on automotive lighting.  His website has more than anyone would want to know about headlight tech and upgrades.

 

Don't know where you shop but ATF+4 can easily be had for about $4 a quart at Wallyworld.  It's one of the tightest trans fluid specs so any licensed ATF+4 product will be virtually identical.  The spec calls for the exact additive package from one specified supplier and gives the blender only two base oil choices also from specified suppliers.  It's a very good synthetic atf but is getting a bit long in the tooth, design-wise.

Our's used to carry it, but I can't find it at any Wally's in my area. Cheapest was Advance Auto, had to get I think Castrol brand, it was 6.99 a quart. Speaking of that, I have 5 quarts and a filter on the work bench :wallbanging:  add it to my scroll of to do list.
