can the automatic take the abuse

[corey796]

i know the manual is good but will the automatic live up to it ?
does any one know what else it has been used in?
i would like to have it tuned and add bolt on's for another fifty hp i dont know if i should order auto or not thanks

I think the Auto will be able to handle some more power. A couple of the stangs at the SEMA show were supercharged and had the Auto Tranny. To my knowledge its the same auto that is in the Lincoln LS and Jaguar but like everything else I am sure there will be Upgraded parts available soon for the Auto Tranny also!

 

[royb]

i doubt it

I know it's a new supplier and transmisison but I think if you race or drive your stang hard alot it won't last long. but hey you got a three year warranty and oyu can get an ESP to cover it longer.

 

[corey796]

which jag

the xkr has a superchargered 4.2 v8 making 390 or 400hp if its the same trans that should be good

It's not a new transmission. It's the same tranny that's been in Jags and the Lincoln LS for several years. As someone else stated, there are Jags making around 400HP with this tranny.

You are partially correct, Tom.

The trannie is the 5R55S. It has been used in the Lincoln LS, T-Bird, Jag S-type (standard auto) and the Explorer since the 2003 Model year. It is very similar to the 5R55N trannie which went into production in 1999 and was used in the same vehicles.

However, the Jag S-type R uses a 6 Speed ZF auto trannie, not a Ford 5R55x trannie.

The 5R55 tannie is rated at 550 lb ft - intermittant duty. While 550 lb ft may sound like a lot, the torque converter can give up to a 2 :1 torque multiplication. How Ford gets away with this is by using the engine managment software to limit torque during shifts.

I would prefer a trannie that uses more robust internals, but I think most customers will be OK with the auto trannie. Those that modify the PCM code and remove the power limiting are going to open up a can of worms.

Chances are, those are just show cars. The superchargers where just mocked up to show the public what the product could look like. Unless the car was a specific race car, id say mock up.

Ahhhh...then I stand corrected. At any rate, it's a vast improvement over the outgoing auto that's for sure.

thanks for the replys

well it looks like a 5 speed it will be i was hoping to try and mod the trans shift points, how hard it shifts and any thing else the programmers that will be out for the car but keeping the grand for up grade will let me do other stuff

 

[fr96ss]

if you are going to drag race, the auto trans is the most consistant. shifting a 5 speed is slowly becoming a thing of the past at the strip.

 

[tjones2]

I believe that 6 speed auto tranny in the Jag is also a new tranny within the last year or two, before that the Jag had the 5 speed auto tranny also.

Good info. 351CJ

 

[slegos888stang]

it shoule take some pretty good abuse but never rule out buying a built tranny if you are gonna do some hard core racing!

I am pretty sure that the 5spd tranny used in the Jaguars with 390HP was from Mercedes (my dad had 3 of these cars).

Was manually shifting ever considered better at the strip?

As I posed above, the 6 speed Jag trannie is made by ZF. Mercedes probably uses that same ZF trannie as BMW also uses it.

The 5 speed Ford trannie is still standard on V6 S-types, the 6 Speed is optional.
