I have a 1995 Ford F-150, 4x4, 5spd, with a 4.9 inline-6. It just rolled over 194,000 today. I changed the oil in it today, and I was inspecting it and I noticed that on my transfer case, down by the drain plug, there is a nice little hairline crack coming from the plug. Whoever the idiot was that changed it last must have used an impact wrench on it!

Anyway, if this motor ever decides to quit on me, which it probably never will, I am looking at a few different possibilities for an engine swap. First things first, can anybody tell me what transmission I have now? The numbers I found on it are as follows:
F1TA
GC
B805916

The transfer case numbers are as follows:

Borg Warner
13-56-065-910(I am assuming this is either a part # or a casting #)

On the tag on one of the rear bolts:
BO25 1 1356-78
160258 F5TA-HA

 

I am sure there are books out there with those numbers, but if you are the original owner, and/or you are sure the tranny has never been swapped, you can get a code off of the sticker on the inside of the door on the driver's side...The stickers should have something like a heading that reads "trans" and a code underneath that...

Give us that code, and it will likely be a quicker ID...

I am going to say you have the Mazda Tranny with the inline 6 and it being a F150 I have a 302 and i have the mazda. If it were a F250 it could have had the ZF tranny.

 

What can you tell me from this?:

Trans: M
Axle: 19
Springs: KI

Also, what axle do I have and what can you tell me about the springs from this code?

Thanks.

 

OK you have a Mazda Tranny 3.55 rear end NON limited slip and the spring codes just give me part numbers. I go this info from a Ford Service CD i bought off Ebay for 15bucks. It comes in handy you should look into getting one.

 

What kind of horsepower and torque limits are we talking for a tranny like this?

 

I have 275 give or take a few and it does fine. I would say if you go more then like 300+ you might want a ZF but i am not really sure on this.

 

are you talking hp or ft-lbs?

 

HP i forgot what i had for tq LOL

 

I'm not sure about hp yet, but I will probably be running in the 400 ft-lb range.
