tr-3650 questions

[Marvin97]

I have an 01 cobra motor in my 97, along with the 3650. My speedometer doesn't work since I did the swap. Is there any way to make it work? Its not the gear in the cluster, it always worked fine before the swap and never has worked since. I was told it wouldn't work because the signal is different from the t-45 and the 3650. Any help?

3650 came in cars that have an electronic speedo, our cars work off of a mechanical speedo that is in the trans, Thats why its not working for you.

pro-motion sells their 3650s with options for either, maybe give am a call and see what they say.

my 96 cobra has a electronic speedo.. no cable.. the 94/95 might still have the old cable drive....

i thought it wasnt until 99 that you could use a tuner to calibrate your speedo if you got different gears or etc.

i know when the 3.73s were put in my car a new speedo gear was installed as well.

I guess you need this...

SPEED-CAL, 1994-2004, 5 SPEED, EXTENDED RANGE :: Transmission Components :: Drivetrain :: Mustang Parts & Accessories Superstore - 1800Mustang

CJK440 is right, this what you need.
I have a tr3650 in my 96, after I installed the SpeedCal, my speedo read perfectly.

do you have the stock t45? my 96 has a speedo cable/not electronic. I know I do because I've changed rearend gears a couple times and changed out the speedo gear in the trans along with it.

The speedo sensor is mechanically driven on the 94 up to 98? cars. Which is then transfered into an electrical signal. (VSS= vehicle speed sensor).

So one can either change the speedo gear to compensate for the rear end gear change or get something like Speed-Cal from Dallas Mustang.

The 99 up cars use a electric/magnetic speed sensor, rather than the sensor being gear driven.
