AOD to T5 - new speedo cable needed?

[MYSTICSVT]

I'm getting ready to do my AOD to T5 swap in my 89 LX and I'm wondering if I need to swap in a 5spd speedo cable. The dealer shows different part numbers for each(AOD versus T5). Anyone know what the difference is?

I'm interested in this topic. I just bought a mustang w/ a similar swap. The guy says it has a new speedo cable but the speedometer is wrong. The faster I go the more the discrepancy. I've got a new speedo gear that I will install this weekend.

I wrote this to say I'm interested. Sorry I don't have an answer.

Never done the coversion, but I am going to say no. The speed sensor that the speedometer driven gear goes into is universal, so I would see no need to change your cable. I read that you need to reroute the cable though because it is routed through the clutch cable hole.

the little gear on the end is different thats it you can change the gear but either will work.

no need for a new cable. you need a new speedo drive gear ( depending on the year of the tranny, a t-5 will have either a 7 or 8 tooth drive gear, 83 to 89 uses one gear for a given rear gear ratio- 7 tooth tranny drive gear, 90 to 93 uses another because it's an 8 tooth tranny drive gear) and you need to re route the speedo cable to the plugged hole in the firewall ( an aod has the speedo cable going through the clutch cable hole).

speedo cable

i did the swap all i needed was the gear like everyone stated before. All the swap articles i read said i would have to modify my reverse light wiring harness for the back up lights to work i just unplugged the extension and it plugged right into my t5 tranny i have a 91 im not sure if this will work on different years though!!

I just did the T-5 swap on my car and when I got the new speedo gear for the T-5 I couldn't fasten it to the cable with the retainer clip cuz the little metal shaft the gear sits on was too long. I had to trim the shaft to make the new gear fit, but it was no big deal and definitely did not require a new cable.
