I am looking at a 1997 4x4 F150 with a bad transmission, how much work is it to put a 1999 2 wd Auto in it out of a 1999 F150.


I imagine you are better off rebuilding the stock 1997 and keeping the 4x4 but this is a work truck so I do not care ... Thanks..... and happy holidays.

 

You would need to decide how much work your willing to put into the conversion and is it worth it.
1. Remove the front drive shaft.
2. Remove the rear drive shaft.
3. Remove the 4x4 trans.
4. Look at the harness and plugs for compatibility. You will not use the transfer case motor plug.
5. Drive shaft length to fit your truck's wheel base.
6. Speed sensor needs.
7. Issues to be solved as they come up.
Best to find a doner truck so all parts you need are available.
Good luck.

 

I have a doner 2 WD 1999 with a locked up 4.6, I can get the 1997 for 1500 or less and it appears to be in good shape besides the tranny...


Just another project I won't finish, do the 97's have any major issues ?


Thanks for the help...

 

the newer the truck , the better. That being said, not a major difference in reliability between 97 and 99..... would have more to do with the maintenance done to the truck in the last 20 years... how many miles.. what suspension / body parts are worn out.

After the transmission swap, you leave off the front drive shaft. Leave the front pumpkin in place with the axle half shafts. They hold the wheel hub/ bearings together. Leave off the vacuum operated hoses to the axle so the front end does not engage.

 

It's a way for me to fix my 99 or the 97,. What is easier swapping the motor to the 99 or the tranny job. The 4x4 is a cooler truckkk...

 

The output shafts are different. Both trans would have to be torn down to swap the shafts.

 

yOUR SAyING FOR THE DRIVE SHAFT SPlines ? I know I would probably need to customize the drive shaft.


I love the way 4x4's look but I have no use for one.....


Thanks for the info...

 

well they have the same motor and rear end... and the transmission is different ? Why would the "shafts" have to be changed ? You move the transmission and the rear drive shaft from one truck to the other. Unless one is a long wheel base, they should bolt right up ?

 

I believe that the shafts would likely have different dimensions between the RWD and 4x4 models. I don't know if the rear ends are different, and if that would play into it at all.

 

I HAVE NO WHERE TO KEEP ALL THESE TRUCKS, MY BEST BET IS TO SELL MY 1999 AND CONCENTRATE on my F 350's and keep them up.


I ruined a completely good truck when the water temp gauge went bad and it was low mileage too..... Thanks for all the help......
