Postby hassy21 » Tue Jun 09, 2009 2:38 am

Loss of resistnace to wheel roll and resistancve to drivetrain roll? Whatever it is, keep track of it and report back to us.

Is your acceleration any slower than before?

ya on my other post i put that i lost about 20 mph on top end but thought that the tires made the speedo that far off but the egt loss make me think it is the converter. the tranny only has about 3,000 miles on it with a rebuilt stock converter.

Rebuilt stock convertor answers your questions. They are junk at best. Change your convertor for even a Hughes and you will notice a difference, to say nothing of a DTT or Goerends Bros.

Sounds like for some reason you aren't getting as much throttle travel anymore. Have you had someone floorboard it while you look at the linkage on the pump to make sure it is pulling all the way against the high idle stop?

Bigger tires and lift should make it run hotter because it has to work harder to accelerate and cruise at the same rate as before. At least it did on mine.

ya i had someone floor it and i checked it it was a little off from what it was before but i wouldnt think i would lose 300 to 400 degrees. i adjusted the timing and lost a little more travel also. how would you get more throttle without buying a new throttle cable(assuming it has stretched over the years)?

The linkage with the 2 ball joints on the end should be adjustable. Just make it a little longer or shorter to accommodate the timing adjustment.

Adjusting the rod should have no effect on idle speed. You should have full travel of the linkage so at rest it sits on the idle adjustment scew and at WOT it should be hitting the afc housing on the pump.(or the high idle screw if u still have one) If it does not hit those items then you don't have full travel. Loosen both nuts on the rod with the ball ends. adjust it so at idle your linkage sits on the idle screw. then have some one push the pedal wide open. If it doesn't go all the way you can try a number of tricks to get it to move further. Some guys find it handy to swap where the ball end attaches to the linkage. They swap it to the hole where the return spring used to be, this gives more travel. (there is another thread on doing this with pics if you search) Anyway basically you need to get full travel because just a little lost throttle makes a huge difference, at least it does on my 2 trucks.

my cable linkage is in the right spot but i found that the spring deal that is attached to the bracket on the side of the block was bottoming out and not letting me get full throttle. so i just cut it off and also adjusted my skinny pedal like 1 1/2". feels like the 20 mins. of work that i did got me an extra 50 hp!!!

my egt's are still maxing out low. since adjusting the throttle it only hits 1200 degrees. any ideas? what is a good converter if that is the only possible problem?

Your either not loading the engine ( slip ) or your not getting as much fuel as you were getting before.

You want to talk to Dave Goerend if you want a new converter. [/u][/i]
