I have a 1991 Ranger with a 302 and WC T5. I recently got the truck and ever since i've owned it the transmission has acted wrong. Sometimes it'll bounce out of 2nd, and end up grinding and not engaging, other times is butter smooth and i have no problems. It'll sometimes grind shifting and down shifting into first and reverse. Also sometimes the T5 just wont find 3rd or other gears at all, and takes everything I got to put it in gear. Whats the deal? do I have to rebuilt the transmission or should I look at some other things before

My old trans in my 88 would pop out of 2nd. I made sure everything was adjusted properly, tried a new shifter, made sure the bushing was at the end of the shifter ball, No luck. I had it rebuilt, sold it and bought a new Z trans.
 
The trans is worn out. Second gear dog teeth are worn causing it to pop out of gear. It needs a full rebuild with hard parts. Just a rebuild kit will not fix it.
 
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 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.
