-> and I'm looking for info on the T-5.  The info I'm looking for
-> includes
->      1. Where can I get a good used one for less than the $600 the

 Local (here) yards want about $750.


->      2. Where can I get info on what T-5s went in what
->         Camaros/Mustangs/etc.?

 Up until a few years ago, all Mustang T5s were identical except for
ratios and all Camaro T5s were identical except for ratios.  The GM T5s
sit at a 20 degree angle to the left to move the shifter over.  The
Fords sit straight up.


->      3. Where can I get dimensional info on the T-5.  Local libraries
-> have            few auto tech books ...

 The tailshaft and input shaft lengths will vary according to the
original application.  The input and output splines will also vary.


-> Well, my urges to do an engine/tranny swap in my XR4 have flared
-> again, and I'm looking for info on the T-5.

 What engine do you have in there?  The 2000/2300?  Just use a T5 from
the equivalent Mustang engine with the flywheel, bellhousing, starter,
and drive yoke.  If it's the 2.8/2.9 V6, you'll have to see if the T5
was ever available behind it, perhaps in the Ranger pickup.

 If your engine doesn't match anything that originally had a T5, you'll
need machine shop work.  Not hard, but it can be expensive if you don't
have access to the proper tools.

The T5 normally uses ATF. Hot Rod says the trans will be more durable
with a high grade synthetic engine oil instead, though shifting may be
sluggish when cold.

McLeod sells an adapter/spacer to put the T5 on their standard steel
bellhousing. Appears to use the standard mounting pattern, could be used
for normal Ford bellhousings to allow 351C, 260, 6 cyl, etc to use T5.
Might be adaptable for anything their bhsg fits.


Hot Rod, May 84, said the T5 was originally designed as a 6-cylinder
universal-application box. They claimed that, properly prepped and taken
care of, it will stand up behind 500hp engines. Claims T5 is closely
related to SR4.

Hurst sells a spring hit to change the feel of the shifter, plus a
complete shifter assembly.

ID number is on a tag or stamped in on the left side of the case near
the main case and tailshaft joint.

most GM have the same bolt pattern and input shaft length. Number of
splines may vary according to original application.

Ford, AMC, and Nissan are the same

Camaro/Firebird have the trans canted 30 degrees to the left

Ford SVO shifter assembly is from Hurst, different from stock

Borg/Warner advises the T5 needs special fixturing for reassembly.
