I picked up a T5 transmission for my '93 (AOD to T5 transmission swap). I'm trying to get a speedo gear for it, but I'm not positive what year T5 I got. Can someone decipher the code for me?

13-51-097-901


Thanks!

Dave

Easier way!! 85-89, and 90-93 T5's are the same respectively. I know that the 90-93's are slightly beefed up, but I'm not sure of what the exact gear ratio differences are. Here is what I would do.....find out what the differences are in the ratios(if any), and stick the trans in each of the five gears and start counting turns. Don't forget...you can always call ford with that part number and ask .

wait a sec...I was just thinking...it shouldn't matter. Unless there is some difference between the way the gears mount it shouldn't make any difference. You want the spedo gear to be calibrated to the gear in your rear diff, not the trans. SO, unless there is a problem with connecting it, it doesn't matter.

Actually, there is a difference. The internals to the tranny determine whether it's 6,7,or 8 tooth gears. The rear would determine the ratio that you need, but the internals to the tranny have to be known also to mate it up correctly.

I have done some investigating and found that there are 3 different numbers on this particular tranny. I am starting to sweat being taken for a ride. 13-51-097-901 is on the cover plate. On the side of the tranny is another number that says 13-52-065-904. Then on the cover of the shifter input on the tranny it says 13-52-066-904. All numbers are prefixed with "Borg & Warner".

I found this link that spells out most of the numbers for Mustangs/T-Birds:

http://66.96.130.106/archives/2000/09/t5swap/index2.shtml

I don't have a clue where to go from here..

Still need a crossmember, too. Anyone?

Dave, I was hoping someone would chime in with info on the numbers you've provided. When we swapped emails regarding the tranny info, I was hoping you'd be able to ID the tranny cuz I knew I wouldn't know!

As for the crossmember, I've seen quite a few for sale on ebay as I've been searching for parts for the Silver Fox. I have no idea how much they're going for though.

I have heard that the numbers I am pulling off are just casting numbers of the different plates that make up the shell of the tranny. I'm told there should be a tag on the tranny that would ID the tranny as a whole. Unfortunately, I see no such tag.

This may turn into a trial and error method as far as the speedo gear goes, before the whole thing is over.

I've got a couple of leads on the crossmember, but nothing solid yet.

Thanks for all your help guys!!

Wait a sec...which gear are you looking for? 6, 7, or 8 teeth? I'm lost...I thought the cone gear that goes into the side of the trans had like 20+ (23 for 3.73's? something like that..) teeth, and I know that ring gear on the ouput shaft has more than 8. At least...I'm pretty sure it did. I haven't had my trans out in a while. Are you looking for the gear that plugs into the transmission, or the one that actually rides on the output shaft? Or is there something here that I've missed? The tag you are looking for is usually under one of the bolts that hold on the tailshaft housing. I figured that's the number you were looking at, but either way I don't know how to decifer that...sorry. Anyway..it shouldn't matter. Just get a set of gears(the one on the output shaft and the spedo cable gear) and change them as a pair calibrated for your rear. Then you should be all set.

Speedo drive gear, Mike. He wants to get a driven gear for his new tranny setup so his speedometer will be as accurate as possible, so he needs to know what his drive gear is. The drive gear isn't the same in all T-5's, according to the info I have. I shared that with Dave so now he's trying to ID his tranny so he knows what kind of drive gear (ie, how many teeth it has) is in his T5.

Get me a 1352-000-***** type of nymber and I can help. As far as I can tell, all of the numbers you have listed are engineering numbers for the cover, or case only. I need somehting with three zeros in it.

Yeah, I know what you guys are talking about now. I was chatting with matt, and he had the same problem. Apparently that ring gear has different teeth depending on what year the trans came from. There are two very simple solutions to this problem. Either get a set of spedo gears(ring and cone gear) OR pull the tailhousing off and count teeth. If the trans is sitting on the ground the second one is cake, and shouldn't take more than a couple minutes. If you need to know how to open her up(not a bad idea anyway to check the condition of the trans) let me know. Hell if I have the day off, I'll come down and do it for you .

I've been all over this dang thing, and there's no 1352-0000-**** number on it. There is one small "tag" in an L shape, but it has no number on it. One of the cover plates has a circular enscription with an 83 in it. 1983? Hell, I don't know.

The port where the speedo gear goes is empty (I was thinking I could pull it and match it to my rear size). No dice there. If you look down inside, there is a white plastic worm gear on the tranny itself that would drive the speedo gear. The start and end of the screw drive mechanism is fully visible through the hole. The start and end line up and there are 6 full passes of the thread between the two. Therefore I am sure that I either have a 6 or an 8.

And then there were two....

So when's your next day off Fishtail??? I'm not sure what good it would do to pull the cover off, when the gear is fully visible? Thoughts?

I'm thinking it should probably be a code 115 from my link in a previous post.

I agree. Seems there should be a bull tag on it, but it's missing. The start and end thread are in line with each other with 6 full threads in between. So it's either 6 or 8 depending where you start/end the count. 'course if you partially rotate it, you'd have 7.....sigh.

I'm thinking about taking the whole thing down to the dealer and seeing if someone there could ID the whole thing and tell me what gear I'd need.

Why not just pull the tailhousing off and count the edges of the teeth on the gear?

The 1352 number will be on a metal tag on the tailshaft housing bolt. If it's gone, then you don't know.

The 83-89 cars had 7 tooth, the 90-95 cars had 8 tooth.

The 7 tooth is yellow, the 8 tooth is green. Pop your speedo cable out and you cna probably tell the color with a flashlight.

Your '93 AOD should have had an 8 tooth drive, so if it's green then you are golden.

FT - The problem is that the gear looks more like a wood screw that lays sidways in there. It's not as easy as counting teeth. Depending where you start counting, you can get a different answer. That's what I was trying to say by the start and end point line up. Depends what part of the "screw" you line up to count.

Mav - There were actually 6,7,or 8 "teeth" on the speedo gear. The '79-'83 Motorsport 5.0 T5 had only 6 teeth. I'm concerned that it might be the one I have due to the insignia in one of the covers with an "83" on it. Pulling the speedo gear would tell me what's in there now (I agree - probably green), but I still wouldn't be sure that it would mate up with the one that's in there. The bull tag is definitely gone; I went over it thoroughly last night.

I think I'll throw it in the back of the truck and run it to the dealer Friday and see what they have to say. I'm hoping they'd at least be able to tell me how to line up the screw to count the threads. That's really all I "have" to know. I'll report back.

Thanks for the help, guys!

Well, I took the tranny down to the local Ford dealer this morning. Found the resident Mustang nut (they actually had 2) and he offered to come out and look at it. He determined it was a 7 tooth and sold me the proper gear for it ($6). He had a '94 GT vert and started talking shop. Before it was over, he had popped his hood and showed me his goods. Also sold me some stainless steel window sill plates for 1/2 of retail (miss order) and I got the rest of the boots I needed. One wasn't in stock, but he said he should have it tonight. Said he could get me below catalog prices on a lot of stuff, to come in and visit more often!

Gotta love it!!

Well, I packed it up and took it down to Prince Frederick Ford this morning (bad luck with Aldridge). Met the local Mustang nut (worked the parts counter). Explained my problem, and he came out and took a look. He decided it was a 7-tooth and sold me the speedo gear for $6. Then he had a pair of stainless steel window plates for $29 (a little more than half of retail) that they ordered for his '94 but were mis-ordered.

Before I left we were talking shop and I got a tour over his '94 GT vert. Pretty nice ride.

I got offered discounts off of many different vendors that they stock and was told to call him before I ordered anything!!

It was a good day!!

Get my crossmember in the mail, and I'll be ready to swap!

Figures I leave for NY on the 15th!
