Transmission from a newer car?

[Shane]

As far as I understand in my 96, the only transmission I can use is the 96-98 style to maintain use of the speedometer due to the gear. Is there anyway to use a newer trans, say 99-04, and make it so that the speedometer works? Thanks

As I remember, you'll need the '96-'98 output shaft and the '96-'98 tailshaft housing transferred to the newer T-45. Yes, this will require disassembly of both gearboxes as the output shaft comes out from the front. Not fun.

[GDTrumbo]

Not sure. Probably have a very similar situation there.

You may want to send a PM to JR, he is the Auto guru here ....

but im pretty sure there is a difference in the vss out puts from the aod cars to the 4r70w but as far as in from the different 4570w years Im not 100% ask him and he will direct you correctly.

i'd like to know this aswell. i'd like the ability or know how on swapping a newer 4r70 in should the need arise....

On manual transmission car's, the mechanism for a speedo gear remained until mid 00 when there was a minor switchup in Mustang drivetrain part's, like the switch in heads and flexplates at that time.

However, in either case, a Dallas Mustang extended range speedcal can be used to coordinate the two different signals, it could also concievably be used to swap a newer electronic odo dash into a SN.

On 96-98 car's, although they do have a gear, they also have a VSS that sends s signal up to the dash, so it's not really cable driven like say my 83 F150 is.

so when i do my gear change on my 97 can i just get the speedo gear for the tranny

3.73 is the highest gear ratio tranny gear i've found. if you get gears higher than those, your speedo will be off without the DSC.

hmm, i'm still confused.

say i bolt in a 2001 auto trans into my 96, is the speedo the ONLY problem?? i always thought the electrical connectors were different.
