I'm in the process of swapping a 518 from a 92 and have some questions a I havn't found answers to. I swapped the throttle valve from the 518 to the 47rh but I'm wondering if the linkage deal that mounts to the frame and has the 3/8 rod that goes to the bracket with the rubber grommet that is mounted to the tranny, does that also have to be swapped from the 518 to the 47? Reason I ask is the 47 bracket is mounted with the grommet pointing up and the 518 bracket is mounted with the grommet pointing down. The other question is about the throttle cable. Someone said the first gen cable is a pull cable and the 47 is a push cable. What does that mean and what do I do about it? Which cable do I use and how do I make it work?

 

shift lever mount use the old one. frame mounting Move it back put the front mounting bracket hole in the rear frame hole and drill a new rear hole in the frame. Did you just swap the 518 throttle valve lever to the 47rh . If so just use old Throttle valve cable. you dont use any of the levers off the 47rh use the shift lever and throttle valve lever off your 518 and use the throttle valve cable that you used with the 518. few other things you need to do is move the trany mount back 1" and make some cleance for the new starter ken

 

What is the reason for not using the shift lever from the 47rh? I already had it installed before I had any answers and it seems to work fine, it goes through all the gears with the shifter.

 

Mine works fine too with the 47RH shift lever (and I prefer it). The only thing I used off the A518 is the TV lever on top of the shift lever, since the clocking is different and it is matched with the 1st Gen linkage.

 

I almost have the swap completed. Just need to get the 3 wire plug for overdrive and lockup. Anyone know how to wire the lockup switch? Also what is the single wire coming out of the governor port? Where do I hook that up at? I had to notch the transfer case shifter bracket to clear it.

Thanks, is it the same for the lockup switch? How do I wire the lockup switch with a pressure sensor and also a switch so I can manually control it?

Finally got it all wrapped up today and lifted the back end up in the air to see if it worked before we took it outside. It does work but I cant find overdrive. When I put it in drive it doesnt shift by itself, seems to be starting in a higher gear and staying in. Then when I put it in 1st it goes into 1st, when I put it into 2nd it goes into 2nd and the same for third but like I said, no overdrive. For the overdrive I got the 3 wire plug wired to the original 2 wire plug, the bigger blue hot wire into the middle of the 3 wire plug and the wire to the front of the pickup on the 3 wire plug, to the other wire from the from the 2 wire plug in. So why am I not getting overdrive? Also on the torque convertor, do I just run a wire from one side of the pressure switch to the torque convertor ground on the 3 wire plug and from the other side of the pressure switch, just ground it to the frame? I really need some help, I have to be heading home from South Dakota to Washington state and I'm driving this pickup with overdrive or not and lockup or no.

I have my overdrive manually controlled with a button on the shifter and lockup controlled with a dimmer switch on the floor. It takes a few mile to get used to everthing, but i prefer being able to controll it manually.

 

bump, why don't I have overdrive or lockup?

 

I figured out why I didn't have overdrive or lockup. The 3 pin connector I got from PATC doesn't plug in quite right. On the female end that is in the tranny the pins are set more towards the driver side and to the other side there is quite a bit of space between the pins and the wall of the connector. Also the locating tab on the male end plug in isn't in the right place. I took a utility knife and cut off the locating tab so it could plug in. What I found out is the plug can plug in without being connected to the pins. Anyways once I did all that work and cut the tab off I plugged it in right and everything worked. Only thing I wasn't happy with was the way the pressure switch worked for lockup. I couldn't tell when it locked up and then it wouldn't unlock, it would start to stall the engine before I put it in nuetral. I just wired it to a rocker switch and am running it manually. If anyone has questions just ask and I'll answer the best I can.

 

Instead of a manual switch or the pressure switch, use a delay on relay piggy backed to the OD wire. Lock up will only come on after OD and will disengage when when OD does. You can still add a manual override switch. If you want to do a part throttle unlock, you can install an adjustable pressure switch in a turbo boost line to unlock it over X psi boost.
