What Ashish said, plus you would need a new spedo gear ( I needed an orange one, I think, with the 3.08 rear)and you would need to re-pin the harness, which is not hard to do and results in a cleaner-looking install, IMHO.
The pistons will already be the right kind, but you may want to change/subtract springs from them. Many of the plate holes are improved, but I'd still do the J-mod drilling to the 01 VB. the changes wont be big but you'll like it.
Doing the J-Mod on a newer transmission is a cake walk. Just remove the springs you want removed and drill the valve body. Everything else is updated.
Re-pinning the harness can take a while. I found it was MUCH easier and nicer to disconnect the harness from the car and bring it inside and do it there with the diagram sitting on the table in front of me. It took about 45 minutes to repin.
For the speedo tooth gear. I just took the one out of the tail shaft of my old busted transmission and swapped it into the newer transmissions tail shaft. It was easy to do when they were both out of the car.
Yep,the Tbirds use a 7-tooth gearing on output shaft for the VSS,and the purple 21 tooth is for the 3.73's using the 7 tooth.But for the 8 tooth,you'll need that queer 23 tooth that is hit and miss for durability.It's not a parameter that can be changed via the EEC.The Tbird and '96-'98 GT use an analog signal whereas the '99-up Mustangs use a digital signal that can be modified via the EEC.The other option is to get a speedcal and it should work fine.The 8 tooth output shaft uses the 21 tooth gear with 3.27's.
LX, you got alot more miles from one than I did. I couldn't get more than about 100 miles out of one. I even tried to machine one a bit. The problem is the helix angle and the depth of the teeth. I machined the OD down on one and then re cut the teeth on a milling machine but the teeth got too thin. I went with the speed-cal and all is GOOD.
Yes there are other threads on the subject, but I haven't found one that addresses both at the same time.
I have a 1996 Mark VIII.
It is tuned with Quarterhorse and has dual cat back exhaust which has made a difference up top/on the highway for sure.
Around town though, it is still...
Not sure if any of you have seen this, but this would make the rear hub swap much more affordable. I was going to re-drill my purchased hubs, but @99.95, I'd rather have new with zinc coating.
Maybe I'm just dreaming here, but that's why I'm asking. I've been driving my dad's '99 Explorer for the last few days and I really love it, specifically the tranny. The five-speed auto does a great job of keeping the SOHC 4.0L V6 in it's powerband, and it is sweet to get on it and a shift only...
I was wondering who uses overdrive (O/D) when driving around town (speeds under 55). I am always flipping the O/D button depending where I am driving. Does it cause wear to the trans. if the O/D is disabled for extended times. At constant highway speeds I always enable the O/D.
When accelerating then letting off the accelerate Im getting a slight clunking from the rear of my car, it's mostly when the car is cold, sounds like something is knocking back and forth in the trunk area, haven't got a chance to get her on a lift yet. Not sure if this is a problem people run...
