Hello everyone,

Im new to this forum and Broncos.

I have two questions. Will one quart of type A tranny fluid hurt my Bronco? The fluid said dexron mercon on the back. The reason I added this type of fluid is because it was low on fluid and that is all the store had. I think it should be type F but Im not sure. I need to find the leak since it was low but wont get a chance until this weekend. Will driving the rest of the week on that fluid cause damage? The bronco is 1993 with an automatic (not sure what type) and the 302 5.0L.

Thanks.

Welcome to the group, glad to have you. :) /emoticons/[email protected] 2x" width="20" height="20" />

The 93's used an E4OD that takes Mercon fluid. Do you still have the bottle ? If so could you double ck just what type it is. If it was Mercon then you're fine. Mercon-V isn't compatible with straight Mercon but someone recently told me there'd been a TSB put out saying that it was ok to use Mercon-V in Mercon trannys but you'd need to double ck that with someone else. I've never heard of a type-A fluid. See if you can somehow ck the bottle again. You can usually confirm what type yours takes by looking at the dipstick itself which usually has that info stamped on it.

If it isn't the correct fluid you're going to want to change the transmission fluid & filter. Adding non-compatible fluid will cause all of the fluid to start breaking down. How much "bad" fluid added will change the time it takes for all of it to go bad but it will still happen. I understand that you needed to add it right then & there but using an incompatible fluid will ultimately result in transmission damage. Before you DO change the fluid & filter find a way to double check just what it was you added but if there's any doubt and you can't get the info about what was actually added then I'd suggest being safe & changing all of it along with the filter.

Just for basic info these are the types of ATF that I know of:

Type F -- Introduced by Ford in 1967 for their automatics. Also used by Toyota.

Type CJ -- Special fluid for Ford C6 transmissions. Similar to Dexron II. Must not be used in automatics that require Type F. Can be replaced with Mercon or Mercon V.

Type H -- Another limited Ford spec that differs from both Dexron and Type F. Can be replaced with Mercon or Mercon V.

Mercon -- Ford fluid introduced in 1987, very similar to Dexron II. Okay for all earlier Fords except those that require Type F. As of July 1, 2007, the production and licensing of Mercon ATF by Ford ends. Ford says applications that require Mercon ATF can now be serviced with Mercon V. See Ford TSB 06144 for more information.

Mercon V -- Replaces Mercon. Introduced in 1997 for Ranger, Explorer V6 and Aerostar, and 1998 & up Windstar, Taurus/Sable and Continental. This is the current ATF for most late model Ford products. See Ford TSB 06144 for more information.

Mercon SP -- Latest friction-modified ATF for Ford TorqShift Transmissions only. Do NOT use in transmissions that require Mercon or Mercon V. See Ford TSB 06144 for more information.

Dexron -- General Motors original ATF for automatics.

Dexron II -- Improved GM formula with better viscosity control and additional oxidation inhibitors. Can be used in place of Dexron.

Dexron IIE -- GM fluid for electronic transmissions.

Dexron III -- Replaces Dexron IIE and adds improved oxidation and corrosion control in GM electronic automatics.

Dexron III (H) -- Improved version of Dexron III released in 2003.

Dexron III/Saturn -- A special fluid spec for Saturns.

Dexron-VI -- Introduced in 2006 for GM Hydra-Matic 6L80 6-speed rear-wheel-drive transmissions. Dexron VI now replaces Dexron III and II, and can be used in GM or import transmissions that formerly specified Dexron III or II.

Chrysler 7176 -- For Chrysler FWD transaxles.

Chrysler 7176D (ATF+2) -- Adds improved cold temperature flow and oxidation resistance. Introduced 1997.

Chrysler 7176E (ATF+3) -- Adds improved shear stability and uses a higher quality base oil. Required for four-speed automatics (do NOT use Dexron or Mercon as a substitute).

Chrysler ATF+4 (ATE) -- Introduced in 1998, ATF+4 is synthetic and replaces the previous ATF+3 fluid. Used primarily for 2000 and 2001 vehicles, it can also be used in earlier Chrysler transmissions (except 1999 and older minivans with 41TE/AE transmission). ATF+3 should continue to be used for 1999 and earlier minivans because of the potential for torque converter shudder during break in.

NOTE:Chrysler ATF+4 Must always be used in vehicles that were originally filled with ATF+4. The red dye used in ATF+4 is not permanent. As the fluid ages it may become darker or appear brown in color. ATF+4 also has a unique odor that may change with age. Therefore, do not relay on the color and odor of ATF+4 to determine if the fluid needs to be changed. Follow the OEM recommended service interval.

Chrysler ATF+5 for 2002 and newer models.

IMPORT APPLICATIONS:

BMW LT7114l or LA2634 -- Special formula for BMW transmissions.

Genuine Honda ZL ATF -- Special ATF for Honda automatics (except CVT applications).

Mitsubishi Diamond SP-II & SP-Ill -- Special formula ATFs for Mitsubishi transmissions.

Nissan J-Matic -- Special formula for Nissan transmissions.

Toyota Type T, T-III & T-IV -- Special formula ATFs for Toyota and Lexus transmissions.

NOTE: There are a number of aftermarket synthetic ATF fluids that claim to meet numerous OEM requirements. Refer to the product label for approved applications.

Thanks for your answer.

It said type A on the front and mercon dexron on the back. The only thing I found on type A was that it was used in the 1940's and 1950's. That was the part that worried me. It looked like type F as far as color but I know color doesnt really mean much. Thanks again.

Isn't the Type-A the combo fluid for both MErcon and DeXron fluids? That's what i see more and more of at the parts store, and is OK for your Ford tranny. Look on the back of the bottle if you still have it for an application chart that may list what types of transmissions it's used in. Good info BB78. JSM84
