    I have a 95 3.8 v6. I was given a 5.0 v8 for free so I'm going to do an engine swap. Someone told me the transmissions were the same between the two(which I highly doubt but just making sure). What other parts will I need.

    I'm guessing
    -engine mounts
    -transmission
    -wiring harness
    -8.8" rear end
    -headers
    -exhaust
    -a/c

    Please correct me if I'm wrong on anything and add anything to the parts list

    actually the transmission used behind the V6 can be used behind the older small block ford asn teh bell housing bolt patterns are the same. you will need the proper 164 tooth flexplate assuming an AOD, or 157 tooth flywheel, assuming a T5, that is balanced for the 302 you have. so you can scratch the transmission off your list of parts needed to make the swap happen.

    and unless your 302 is making more than about 300hp or so, you can keep the stock rear end also. you can upgrade it later as needed, so scratch that off your list as well to save money.

    Will I blow out the transmission if I keep the old one?

    T5, all versions used in 5.0 Mustangs
    A Tremec T5 is still the same T5 that is prone to self destruction when used in a street/strip or racing environment

    Tremec 3550/TKO /TKO500/TKO600 AFTERMARKET replacement for T5 - handles racing environments with ease
    A Tremec 3550/TKO/TKO 500/TKO 600 is a completely different transmission from a T5. Strong and almost bulletproof unless you run them without proper lubricant or full throttle shift without the clutch.

    See http://www.ttcautomotive.com/English/products/tremec.asp for more information - check out the "Light Duty" group, since TTC makes monster transmissions for big trucks as well as passenger cars.


    T5 identifier information.

    On the tail shaft of the transmission, there will be a stamped aluminum tag. The tag will have a number on it that you can cross reference to the chart below. There is no other way to find out what type of T5 it is without disassembling it. All the rest of the numbers on the outside of the T5 case are part numbers which are not unique to any particular T5 model.

    Remember that 94 - 97 T5's have a longer input shaft (about 11/16” longer) and can only be used with a 94-95 bell housing unless you modify or replace the input shaft.

    T5's used with a 4 cylinder have a 3.93 first gear, reduced torque ratings and an input shaft pilot diameter that is smaller that the T5 used for V6 & V8 engines. The pilot diameter is .59" compared to the .668" used on V6 & V8 T5's. It requires a different pilot bearing to be used with a V6 or V8. The pilot bearing you need is for a Ford Ranger diesel from AutoZone part #14672

    I don't know how you feel about the DYI thing when it comes to gears, some people don't like the idea of working on transmissions. If the DYI transmission fix idea isn't something that you would rather leave to someone else, here are some resources:

    See http://www.ttcautomotive.com/English/onlineorder/product.asp to download a FREE service manual for T5 or Tremec 3550/TKO
    You will need the Adobe Acrobat viewer which is also a free download – http://get.adobe.com/reader/

    See http://www.hanlonmotorsports.com/ or http://www.ddperformance.com for parts

    A T5 rebuild kit with syncros, bearings and other small parts costs about $160. It does not include any gears or shafts.

    http://www.hanlonmotorsports.com/ also has a video on how to rebuild your T5 or Tremec. It costs about $20, and is worth every penny of it.

    I did a Tremec 3550 rebuild, and it wasn't that difficult. The video was an immense help, and I would recommend viewing it. At $20, it will give you an opportunity to look and decide for yourself if you think that it is something you want to try to do.


    T5 Shim kits – best product I have seen in a while… http://www.5speeds.com/t5/shims.html
    “The Peel ‘n Place T5 World Class shim kit makes shimming T5 counter gear and main drive gears very easy.”

    Do some research before you get involved with this. Even if you have a free engine, it is still cheaper to buy a 5.0 Mustang than it is to swap a 5.0 engine into a V6 car.
