Ltnrisk 104 Report post Posted March 4, 2009 Hey guys, I am sure most of you are pretty excited about summer coming soon as I am. Well anyways I am going to do a auto- 5 speed conversion. The only thing is I am clueless to what would be the right transmission for my 302/347. So far I understand that the T5 is a good option. Are there other options keeping a budget in mind?

Fordrevhead 29 Report post Posted March 5, 2009 Are you looking to buy a used stock Borg Warner GT T5? 85-89 T5's are the same and then 90-93's are the same, 90-93's having stronger gearsets. Some last 10k some last 150k, depends if you get a good one and depends how it's driven. There's a lot of variations of this transmission now and some tough aftermarket ones. When Tremec bought Borg Warner they didnt change this design initially. True Tremec T-5's later were tougher and they made T5 5 speeds and T5 6 speeds. For the amount of work to put it in, I'd personally hold out for a TKO or a T-56. read up http://www.moderndriveline.com/Technical_Bits/t5_history.htm Quote Share this post Link to post Share on other sites
Ltnrisk 104 Report post Posted March 6, 2009 yea I am looking to buy a used one and rebuild. Thanks for the link I understand more about the T5 now. Does it matter at all what year it is, or do they all fit? Quote Share this post Link to post Share on other sites
1BAD351 21 Report post Posted March 11, 2009 I don't know a ton about the t5, but I do know my buddy blew up 2 of them in his 90. I have also heard that they aren't very reliable/strong trannys without some work. Id go with a tko500 if you want a 5 speed. Quote Share this post Link to post Share on other sites
xplane 10 Report post Posted April 5, 2009 I had a 90-93 T-5 in my 68 GT coupe which was a daily driver for 10 years. I had zero problems with the trans. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p> <o:p></o:p> Like Fordrevhead mentioned, how it is driven is a major determination on longevity. I added Cal-Tracs and drag radials a couple of years ago and broke both welds on the spring perches! <o:p></o:p> <o:p></o:p> Stick with street tires and less aggressive driving and you should be fine.<o:p></o:p> <o:p></o:p> Mike<o:p></o:p> Quote Share this post Link to post Share on other sites
CavScout 10 Report post Posted May 1, 2009 Like Ltnrsk, I am looking to do a swap as well. Would a T-5 work with a 390 s code as well? I am considering swapping out my C6 for a manual to significantly improve the grin per mile. I would put my car closer to the daily driver category...vs hard core racing.
