Have a rebuilt trans on hand if anyone has one fail on the road.

[Bob Dunahugh]

It's boxed up to ship that day. I'm in Iowa. Was built by a shop that has built many 425 transmissions for GMC's. Comes with a GM HD Allison torque converter. ( Built my trans in 2004. 91,000 miles on it. Had it in our first Royale. Then put it in our second. And both of our 78 - 403 Royale's have always had a towing load behind it. From a minimum of 17,000lbs, to a max of 25,000 lbs GVW. ) The Allison was not the stock original GMC torque converter used in our GMCs. I don't read the net much anymore. So you must respond by privet e-mail. Or 319-521-4891. Bob Dunahugh 78 Royale and 4 COPO Yenko's
