oil questions on a trans

[Crashtest84]

Well back befor the site mishap I swaped out a 4speed for a 5speed and was unsure of what fluid to use as I was unsure of what yr the trans came from

My truck is an 84 ranger 2.8 it had the 4speed when I got it. Well I came across a guy that had a 5speed trans and transfer case with the longer front shaft I would need. All he could tell me was that is was out of a late 80's maybe early 90's bronco. It looked just like my 4speed trans, so now that I got that info out.

I used a 75wt gear oil in the trans and ATF in the transfer case, but it has gottin cold here in now its really hard to shift the trans when its cold. As in right after I start-up and start driving, after I get few miles in everythings seems about normal so... does this trans maybe need the ATF and not gear oil ?

Yep, drop the pan, replace the filter, and fill 'er up with some mercon atf.

Pretty much all late-model Ford manual trannys use Mercon ATF (not Mercon V) and not gear lube. I agree, drain it (I don't think there is a pan, just a drain plug) and fill it with Mercon. I have a suction gun I use to fill my t-case, one of those makes it easy. Cost about $8.00 at Auto Zone and handy for other stuff too.

If by "Bronco" you really mean "Bronco II" (the difference is VERY important -- watch those details or you'll get ridiculous advice), all manual transmissions with pans use gear oils, and all manual transmissions without use ATF.

and by "longer shaft" and the notes in his public profile saying he has a 1984
would indicate that I presume he has a 2.8 with the crank mounted pilot bearing.

In any event there is no ford 4sp used in a truck that uses ATF.
(there is only one 4sp used in some early Fox Mustangs the T-4
but they are rather rare)

a Ranger/Bronco2 4sp trans is certainly a T-K

if it looks like the 4 speed toyo and has an aluminum pan its probably a 5 speed toyo.stamped steel cover is a fm 145 or 146 right?i can't remember what lube i ran in the toyo trannies i had in my courier.

ya sorry my bad Bronco II yes the "longer shaft" was meaning the front drive shaft seeing how the 5-speed is about 1 1/2 longer. I'm just going to guess that its the toyo trans its a full alum. body trans and I wouldn't so much call its a pan but it has a flat bottom plate that is alum with prob 15 10mm bolts in it with the big drain plug to and last yes it has the crank pilot so.......... is it gear or ATF

Most late model Fords used ATF. Go with the ATF.

NO NO NO NO NO!

It's either a TK5 or a Mitsu FM145/146. I suspect a Mitsu FM146. Every one of those takes GL-4 GEAR OIL.

And we are very definitely not talking about a late model Ford, either for the original truck or the donor.

its got to be the t-k if it has an aluminum pan/cover.be nice to that old courier era tranny its not too strong(more power and weight than the b2000 it was designed for.take MAKG's advise on 90wt.

 

[Crashtest84]

man you guys are confusing ok so what about the part where is will hardly shift into gear when its cold ?

how about and pic will that help ?

 

[MAKG]

DEFINITELY a TK5.

Shifting problems in every gear are either due to fluid (use GL-4, not GL-5) or a clutch problem. GL-5 is for differentials. Those don't depend upon friction to accomplish their function (excepting limited-slip, which requires an additive to work correctly).

The factory calls for 80W. Using 75W shouldn't make too much of a difference. Neither should 90W, but if it's getting cold, I'd err on the light side.

That picture exposes illegal activity. Removing a cat is a federal crime. Probably not a good idea to put it here.

I'm guessing that you are just THAT familiar with it? How can you tell that there is no cat to being with? Is that non-stock piping or what?

Oh well its an 84 model truck and its for off-road use and I live in Oklahoma last it has a farm tag to so by law here it doesn't have to have one

 

[Crashtest84]

hey Agpete139 I see you have bent beams and a superrunner kit.... not installed do you have any pics of that stuff like one of the bracket for the steering kit where it bolts to the frame and like some good pics of the bent beams ?
