So I have a 2003 4.6 hse land rover discovery and u want to swap out the transmission with a 2001 4.0 transmission. Is it compatible?

 

i "believe" so but it will be 3/4 inch shorter

 

I did codes to just swap it out. Can't find the problem and mechanics down here are **** when it comes to landys

 

the unit in the 03/04 was slightly beefier than the 00-02 units, but i think it only came out to approx. 3/4 of an inch longer.
i would assume you would be using the 03 drive shaft and cross member. I would check with of of the sites parters to be sure

 

Hey I got my hand on a 03 buy 4.0 think it'll work?? Mine is a 4.6

 

There were no 4.0 in the 2003. The 2003 and 2004 are nearly identical except for the transfer case. You can exchange anything between these 2 year models. Somebody tell me if I'm wrong

 

search for a transmission from a 2003 OR a 2004. They are very plentiful and no more than $300 for even a low-mileage unit and that price includes shipping.

 

Pretty sure the difference is just the torque converter. I think Ashcroft's website has more details.

 

Even minute as that would be, couldn't make a difference.

 

Hey drowssap so do you think a 02 transmission can work on a 03? Turns out the junkyard owner thought it was a 03 but as I was removing it I was the cdl nipple and I ran the vin and it's a 2003. It's just a little shorter so we can just buy a longer drive shaft???

P.S. thanks a lot man!!
