Thanks to those who answered my "newb" questions about water heaters and the GMC.

I have another fact finding question related to the transmission.

If my understanding is correct, the "stock" transmission for a GMC is a three speed.

I have a three speed on my Empress Triple E (powered by a big block Ford - 460 I think).

In the interests of bringing cruising RPM down to save gas and reduce noise, I installed a Gearmasters overdrive (it bolts on after the regular transmission and requires shortening the drives-shaft). Once installed, it did a great job, bring my revs down to about 2,000 at 60 mph.

Is there a "doable" swap that would put a 4 speed or a 3 speed with overdrive tranny in a GMC? I assume a solution like the Gearmasters overdrive is out because of FWD.

The purpose would be the same: fuel economy and more relaxed highway cruising.

Thanks in advance
