Gearvenors overdrive
 

The overdrive is in & working,I have 4.10's so @ 55mph It was spinning 1950 or so,now 1450 or so. Now around 80 mph@ 1900 or so. It's a good idea to use their elctronics to cut the lockup durring upshift or downshift it was harsh with it locked up even I backpedaled it.The EGT's were up a little but I still have to put on the 4 in downpipe& take off the cat it's still on. The install was pretty easy the instructions didnot tell you to spread the snapring for the bearing in the output extension housing on the 241 t-case(one piece).Other than that, not bad at all.:jump:

How much does one of those cost? Also, where did you get yours?

I just came back from my first trip, snowmobiling on Tug Hill in N.Y. I have to tell you people what HUGE difference on the open rd. The engine ran so nice 1500-1600 rpms@ 60-70 mph or so,have to watch I don't get tickets! Had plenty of pull,I only had the '93 EXT in the back no trailer,some day see if I can pull that double over with out to much stress/heat on 47re

They are nice I'd like to have one but there is so much other stuff I could do with 3 grand like get a set of compounds haha

I use the truck as a truck so just a few changes to suit my needs,I took a 80 mi trip yesterday,so nice to roll down the road 1500-1600 rpm or so,yea big power is nice I have a Chevelle with a 671 supercharger for that!!:tu:
