So I just recently had my trans go nutty on me and took it in for the first time a month ago. I just got it back for the second time since then. I got a hook up from a dealer tech who had to replace the governor speed sensor, torque converter, and a few other things he said routinely die. I had to take it back because the throttle linkage or something like that was loose causing the tranny to go into limp mode every so often and shift differently than when I first got the truck. The guy said that it was because the 47re had a performance valvebody. Now this is the first major repair since I bought the truck a year ago. Driving home today I realized pulling out the lot that it was shifting different. When I first got the truck it shifted firmly at 5, 10, 27, and 45 mph. Now it's not nearly as firm and shifts at 10, firmly at 25, and loose again at 32 mph. I don't want to take it back a third time because that might be the charm to kill my truck and make me broke, plus I'm questioning his abilities now. Goes to show that you get what you pay for right? I want to know if there's a way I can adjust the linkage or whatever without very much experience in transmission repair at all, or should I just go find some one reputable? I'm desperate and me wallet's running shallow. I'd appreciate any advice.

 

Compare position of cable end to attachment stud on throttle body lever:
Cable end and attachment stud should be aligned (or centered on one another) to within 1 mm (0.039 in.) in either direction.
If cable end and attachment stud are misaligned (off center), cable will have to be adjusted as described in following procedure.
Reconnect cable end to attachment stud. Then with aid of a helper, observe movement of transmission throttle lever and belcrank lever.
If both levers move simultaneously from idle to half-throttle and back to idle position, adjustment is correct. If transmission throttle lever moves ahead of, or lags behind belcrank lever, cable adjustment will be necessary. Or, if throttle body lever prevents transmission lever from returning to closed position, cable adjustment will be necessary

 

Transmission cable is adjusted by running throttle to the floor and checking free travel of the arm at the trans.

Sorry, Adjustment is made with throttle at closed throttle. 3 inch lever above shift lever on left side of tranny must be fully forward against internal stop. The lever must move immediatelly with any throttle movement. Proper adjustment allows simutaneous movement without causing the the transmission throttle lever to move ahead of, or behind the throttle. There may be some movement avaliable at WOT. The cable adjustment is made at APPS. There is a tricky lock that must be pulled out to unlock.

 

Thanks. I tried at the throttle arm connection but can't figure out how to take the cable off. Does any one have any pics or know where to get any?!

 

So I get under there and find the cable ends to the trans and throttle linkage, but I cannot find out where to adjust the wire itself. I checked both ends and they appear to be permanently fixed to the cable. Can anyone help me?!

 

 

Using the free travel method is far more accurate and just plain easier.

sweet, thanks. mission accomplished

 

hey johnh, is that a service manual?!

 

yep!.....................
