TC tranny behind 5.0?

March 01, 2006, 05:26:09 AM

Now that I've got a T5, albeit a 2.3 T5, am I safe to use this behind the 5.0, if I can get the engine to hook up in my car-(see my thread in engine tech for that).

I assume I'll need the V8 bell, and clutch, PP, and throwout bearing.
For pedals, I was wondering how much of a PITA it is to use the TC hydraulic, or would it be easier to use Mustang style, with the cable?
I put a T5 behind a 2.3 in my old '86 Stang, but the tranny was out of a newer, like 91 or 92 stang, and I remember there was an issue with the clutch cable, I had to make a bracket for the end to catch in, as the newer Stang's cable used a ball on the end.
(lookin' back, I shoulda knew to pull the cable, too)
And, seeing that the 5.0 is an auto car, would the flywheel work, or will I need to grab a manual one?

Im Pretty Sure Thow The Tc T5 Will Mount And Work, 1st Gear Is Different

A. It is a weaker T5 and wouldn't last very long with some hard launches.

B. It has a useless first gear for a 5.0.

C. You can't use a hydro setup with a 5.0...there aren't any hydro clutches. So you would have to convert to a Mustang or 83-86 Bird 5 speed cable setup.

D. Auto's use flexplates. They have virtually zero rotating mass and don't have a machined surface for the clutch. A flywheel is required.

And there ya go...have fun with the swap or finding parts or...whatever you decide to do.

You will also need a pilot bearing from a 90 Probe, the input shaft is a smaller diameter on a 4cyl. tranny.:D

the 1st gear is going too be wicked steep, as specially for an SO. your not in the power range too realy brake it with an SO though...it should be fine as far as that goes. their ARE hydrolic setups for the T5.....id go with a cable clutch though....you will need a T5 flywheel.

Yes hydro setups for 2.3 T5...5.0's are all cable...there isn't a 5.0 Hydro bellhousing....if there are...sorry for the mistake, but I can't or have ever found a Ford 5.0L Hydro bellhousing.

not factory, no. but there are conversions. guys use them in ranger V8/T5 or Tremec conversions. there is the hydrolic TO bearing and a hydrolic conversion for the T5 bellhousing.

First of all, according to this chart:

http://www.coolcats.net/tech/advanced/t5_data.html

all gears are different, not just 1st.

Next, my input:

88 TC. 89 5.0 HO, stock TC tranny. I've been running the car this way for a few years. I built it when I was 17, so needless to say, i drove it hard, including quite a few decent launches on my Nitto drag radials. Held up AMAZING and I use all gears (just don't downshift into 1st on the street! but then again, who does that in a mustang either, unless parking, etc...)

I actually love this gearing (aside from the mileage drop i most likely experienced)!! I did the math (using the numbers from the chart above) and it basically told me that having a 5.0 in this car with a stock, TC T5 and 3.55's is roughly like having 4.10's in a T5 Mustang.

mid 80's ranger with the 2.2 diesel is what i was told.

i was correct on this assumption... i changed my trans today.

i had forgotten what it felt like to have a trans that shifts:D

The probe bearing fits as well, evidently they are the same.

4-cyl trans info

heres a vid of my car with 4 people including driver with a 4cyl trans from a 91 mustang tearing it up. http://www.putfile.com/cougarman and i broke nothing , heck it doesnt even shift hard to this day. i actually think the 4cyl trans's are stronger than the v-8 ones. im not sure which parts are weaker ive had one apart looks identical to the v-8 accept the 4cyl has a bigger input shaft bearing even takes the same rebuild kit so?

Trust me the 4 cyls not stronger... Drop the hammer on it with some STICKY tires.... it'll break(its just loafing spinning tires). Yes the rebuild kits are the same, as bearings(other than input), syncros, etc. are the same. The front input bearing has to be larger because there are more teeth on tthe input, to give the lower gear ratios in the half motor tranny. Its the extra tooth count(more=smaller/thinner) that weakens the torque rating, as the gears can only be made so large. Unfortunatly the T5 was designed in the early 80s with economy not brute strength in mind.

maybe what some are experiancing is work hardening of the gears?
dunno if it is possible but would seem valid with the constant heat cycles they go through.

the one i took out of my car didnt break on 175h/p shot of spray on full slicks. it just had bad 3rd gear synchros.I did verify it was also a 4 cyl trans.

I hope the new one is just as strong.... so far so good:D
