Drivetrain t5, help
- Thread starter afso
- Start date
I think the input shaft is to long. You might be able to change that out though with a fox one. Also I think the torque rating on that trans it lower than the V8 T5. However I have heard that the T5s out of the 99-04 v6s were much stronger.
You need to swap the input shaft and bearing retainer, but only certain years are interchangeable IIRC, the 90-93 T5 gearset is the same as the 94+ T5 so they would work. You'll need to count teeth to be sure.
I also believe the T5 went to an electronic speedo in 1998, which is a bigger issue. Unsure if the mainshaft has the provision for a mechanical speedo drive gear, but then you'd need to swap the tailhousing.
Might be easier to just find a fox t5

Good thread that details out some of the steps needed to convert.
I'm not sure if 1998 was mechanical or electric speedo

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.
A Tremec T5 is still the same T5 that is prone to self destruction when used in a street/strip or racing environment
T5, all versions used in 5.0 Mustangs
Tremec 3550/TKO /TKO500/TKO600 AFTERMARKET replacement for T5 - handles racing environments with ease
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.
You'll need the shim kit below when you swap the input shaft.
