two T5s, whats the difference? February 15, 2018, 11:17:37 PM hello everyone!During a series of horse trades, I ended up trading off a spare 351W that i had sitting around (basically a core, it ran when pulled, and sat in the corner for close ot a decade) for two T5 transmissions. the first one is out of a 1989 ford Mustang GT, 5.0 car, and i was told, the 2nd gear syncro is a bit finicky. the 2nd one is out of a Merucry Mekur, that had a non turbo 4 cylinder.I'm looking to eventually put one of these into my 87 Tbird, my question is, whats the difference between the two transmissions?

two T5s, whats the difference? Reply #3 – February 16, 2018, 10:40:46 AM The '89 Mustang unit will be not have the improved gear set so the torque rating on that unit will be 265 ft/lbs. The change was in '90. Quote Selected
two T5s, whats the difference? Reply #4 – February 16, 2018, 10:56:47 AM As Chuck stated, no such thing as a XR4Ti without turbo or with T-5.. Possibly someone had swapped a Stang NA 2.3 & T-5 into one?? Or someone was lying or had no idea what they were talking about...Anyway if it's a half motor trans, the pilot bearing nose will be slightly shorter and smaller diameter... With i believe Ranger pilot bearing they fit behind a 5.0... Biggest issue is are weak(rated around 240Ft lb) and have a stump pulling 3.97 1st gear... O/D is only 20% vs approx 33% on V8 versions... Few parts are interchangeable between the two transmissions... It's common for the 1st/2nd gear synchro to be bad, especially if someone used 90W gear lube vs automatic xmission fluid... Usually requires at least synchro & 2nd gear replacement... The newer V8 trans was a little stronger than earlier models... Was possible to shuck the 3rd gear teeth from cluster on a power shift in the earlier trans... Somewhere around here I have a T-Shirt for that one... Quote Selected

GM transmissions had different input shaft, bolt pattern and location(s) of shifter... I bought the later gearset after I blew the one up in my '86 Stang... They must be better cause that one never broke... Gearset and rebuild kit will give you most everything you'd need...There are charts on net that ID trans with source, gear ratio, torque etc...

Reply #13 – February 18, 2018, 10:08:40 AM Quote from: bootleggers deluxe;464655the blue one doesnt have a tag, and thats the one of unkown status.Put it in 1st & count turns of input shaft to give one turn of output... If it requires approx 4 turns, that's said 4cyl trans with 3.97 1st gear... No need to proceed farther... I believe there were lesser ratio 4cyl trans in early TC & SVO but none less than around 3.5... The production HO 5.0 World Class trans all have 3.35 1st gears(note I said HO)... The '83 & '84 non-WC have a 2.95 1st...Here's a list of just the Ford transmissions...http://chris66dad.tripod.com/id38.htmlAND I don't mean to ruin your day -- BUT but if tag on the black transmission is E7SR-7003-AA and 1352-155, that's a 4cy trans as well... Turbo Coupe trans...On this list at bottom of first page...http://www.autogear.net/wp-content/uploads/2015/03/T5wc_Mustang_21.pdf Quote Selected
