I know this has been addresed many times. I am doing a t-5 swap in my Comet 302 motor. I have found a t-5 from a 1988 5.0 motor Mustang. Will this work? I have not seen the trany yet. Is this a top loader? I also need to find a bell housing for it. I think I want to do a hydraulic setup. Can I use my bell housing from a c-4 and cut the needed holes? What flywheel is needed and what vehicles are good for pedals? Lot of questions I know thanks for help.
The t5 looks nothing like a Ford toploader but the gears do go in from the top. You will need the t5's bellhousing to make the swap easy. You need a flywheel to match your engine. 70-up Maverick/71-up Comet pedals for a manual transmission will fit with no problem
You really should verify it's origination, lotsa 4cyl T-5 floating around that are weaker and have gear ratios unsuited for a V8(plus input is slightly different size)... If it has the tag with 1352-1xx(see chart) can tell easily, casting numbers on case are useless... BTW if not on list it could be a Generic Motors transmission, were also used in Chevette, Camero, etc(plus some AMC)... Those have different tail housings and spline counts so can't easily be used in a Ford application... http://www.fordmuscle.com/archives/2000/09/t5swap/index2.shtml
Well I purchased a T-5 tranny today. It is marked on the side 89 Mustang. The number on the main case is 13-52-065-908 checking on chart from Borg warner shows 84 5.0 Mustang. Doing more reading and checking it has a casting year of 89. Checking number on lower right near where bell housing attaches it is an 89. Little miffed about 84 cross with borg warner. What is the going price for one of these? Person said one of the sinkernizers(sp) is bad how hard is that to fix?
the only numbers that help are the ones off the tag that is on one of the tail housing bolts. if that tag is gone then you have to id it by figuring out the parts in it. if its a 4 cyl one, it will have a smaller diameter on the pilot bearing surface on the input shaft than a v8 one. you can find the dimensions with a google search. these are not to hard to rebuild if you follow the rebuilding directions. again lots of how to rebuild t5 stuff on a google search.
So this tranny will work correct. However I need to make sure it is the stronger one. If it is not rebuild it in the same casing correct?
i am not saying its correct. with out the tag number you need to verfiy the pilot bearing journal size on the input shaft to see if its a 4 cylinder or v8 t5. or you can take the transmission apart and figure out the gear ratios. they used different gear ratios for both versions.
The 1st gear of the 5.0 T-5 is 3.35, so in 1st, the output shaft will turn once for each 3 1/3 turns of the input... The 4cyl T-5 has a 3.97 1st, so will require four turns of input for each turn of output shaft... The 4cyl trans aren't worth the time/money to rebuild, even case is machined differently to fit the larger input gear & bearing into front of case(gear is larger because of lower ratio 1st)... Last I heard the 4cyl front bearing retainer is obsolete and not avail, surface the throw out bearing slides on is aluminum are always scored ... Same goes for the 5.0 trans but there is a steel sleeve replacement available...
First Gear is 3.35 so it looks like I am on the right track. Going to tear it apart and check everything out. Make sure it is in good shape. Now I start looking for a bell housing and pedals.
