  1. is the 95gt bellhousing deeper than the fox body bellhousing?'

  2. Yes, its to account for the longer input shaft.
  3. Thanks, do you know what how much deeper the 95gt bell is?
  4. Somewhere around 5/8ths of an inch.
  5. Thanks!! do you know if a 5speed trani from a fox body will make it into the pilot bearing on a 95gt ,at all?
    thanks soooooooooo much
  6. Pilot bearing are the same size.

    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 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 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 –

    See or for parts

    A T5 rebuild kit with syncros, bearings and other small parts costs about $160. It does not include any gears or shafts. 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…
    “The Peel ‘n Place T5 World Class shim kit makes shimming T5 counter gear and main drive gears very easy.”
  7. If its a stock T5 with fox input shaft and bellhousing. Yeah it will engage the pilot. Pilot engagement dont change unless you mix match parts between the two transmissions.

  8. if I put the fox 5speed into 95gt with the 95gt bellhousing will it still reach into the pilot bearing [ part way]

    thank you soooooooo much,, I know a guy that said he did it, but did it get in the pilot bearing enough?
  10. I forgot the pilot bearing hole is smaller on a 4 banger,
    this is a daily driver and i have a good spare 4 banger t-5 , so maybe i can use the 4 banger trani while i deal with fixing the other

    if the in put shaft will make it in to the pilot bearing with a 95gt bell housing and all. At least part way

    I think it will go in half way, couse the end of the in put shat,, for the pilot bearing is about 1 inch long

  11. You must swap the input shafts and bearing retainer if you do it that way.
  12. so the 4 banger trani will accept the V-8 input ? can it be done from the outside? [just pull bearing retainer?]


  13. I'm 90% sure the answer is no. The 4-cyl countergear will not accept a V8 input shaft. I believe the tooth count is different.

    In order to run a 4-cyl T-5 as is, you will need to use a Fox body bellhousing with a different pilot bearing to accept the smaller input shaft snout of the 4-banger trans
  14. but if i run a fox bellhousing in a 95gt the shifter will be moved forward
  15. Thank you everyone!!!!!!!!!!!!!!!! I got all kind of help from experince and common sense to part numbers and links to manuals.
    I am begining to think the trani is ok, I have a sound coming from the car that sounds like a bearing noise, [and Im going to check the front wheel bearing]
  16. Are you putting this in a 95GT? With a name like 89LX, i was assuming this was a Fox. Really need more details of what you are trying to accomplish

    Yes, the shifter will move forward.
