I need to know of any transmission changes in the v6 automatic ford mustangs from years 1996 to 2000. What year models of ford mustangs will fit the transmission of a 2000 ford mustang v6 automatic transmission model?

Question edited for a lot more clarity and remove that bad abbreviation of 'transmission'.
Question moved to model category.

There are three types of transmission

Transmission 5-Speed Getrag F23 manual
4-speed 4T40-E automatic
4-speed 4T45-E automatic
But the years are good
1999-2004 3.4 L LA1 V6

..

the transmission shops re-builders can answer that.
no year car told at ll or 1995 to 2003 and then changed name to freestart. (an 8 year span )
no engine size told , this tells what trans is there.
no VIN told this tells all above .
in most cases, the answer is complex. vast versions exist. even 1 year.

• has to fit engine, bell and and match TC splines
• has to fit mounts/
• has to fit rear end extensions , 4wd /ALW or fit drive shaft.
• the TCM must like the TCC clutch. electric it is.
• has to have correct gear ratios. not cause TCM to go berserk

best is learn what is the now, not told
the car has a TCC
ford AXOD 1991 up is TCM shifted.

1995
4-speed AXOD automatic\
1995 -2003 then AXOD muted to these.
4-speed AX4S automatic
4-speed AX4N automatic

now you know what is there and some top reasons to fail
lots.
why not ask rebuilders this, ?
each transmission has side tag and AxOD is only series transmission name a family, what matte all else on that tag.

in the end ,the TCM must be happy, for SURE.

it has to fit,sure.
and have correct gear ratios
4r70w this is only series number, not any actual transmission #
the TCM (part of PCM) must like it, for sure ratios.

the old box has tag on the side, and is bingo for full and real p/n#

A machine is needed to get all of the fluid out of the transmission. Then, the pan must be removed to replace the filter. It is best to take it to a transmission shop.

if both trans are identical then nothing not sure if v6 will fit v8 like bell housing, shifter location sensors. etc you may also want to think about will the v8 blow the trans from the v6

3,000 miles or 3 months which ever comes first

If you are talking about the axle hub nuts,then you may have to use an air impact socket driver and impact sockets.These nuts can be torqued to over 140 FT LBS. Let me know if you need more help.MOE

Very well could But, I would check the Wiring Harness Connection, They could have Changed Between Years. The Air Bag itself will fit Though.

give me a welder and a set of gas bottles and i will fit anything into whatever you like.but to be honest i do think your biggest problem will be the wiring.want to really hot it up put a jag engine in.but its most likely worth more in its original condition.high compression engine and not subject to having to fit a cat.but you could still fit the manual gearbox though.OK for when your europeon cousins visit as most of us lot in europe especially spain and italy wouldnt know how to drive an auto,they are only for old and disabled people.plus they cost a lot of money extra to have when you buy a vehicle and thats only if you can get it in an auto,very few manufacturers build europeon cars in autos

Possible, but probably expensive.May be able to find used parts and save some$
