rebuild 727 vs getrag swap
 
In the past week my battery exploded, the plastic piece on the throttle linkage broke and left me stranded 20miles from home at 3a.m., and finally 3rd gear is all but gone in the tranny. Ive been pondering whether to just have the 727 gone thru, put a converter and manual valve body in it, or swap in a getrag. What are y'alls opinion? I haven't decided if the truck is worth keeping after everything that has went wrong and is going wrong. Just looking for some advice.

Keep the truck! The Getrag swap would be cool to get you overdrive, but would be labor intensive. In addition to all of the obvious changes you would have to make, I'm pretty sure you would need a t-case that came behind the Getrag. I'm pretty sure your 727 has a 23 spline output where the Getrag has a 29 spline. I think 29 spline NP205's go for pretty big $ because there hard to come by.

I think im gonna rebuild the 727. I found a hughes torque converter with a 1200rpm stall. Any body used one of their torque converters? Also thinking about a tci maximizer rebuild kit.

1200 is WAY TO LOW!!!!!!!!!!!!!! if i had to do it again i would have went higher than 1700 with mine. stock stall is around 2200 look into a 1900-2000 stall.

Im looking for the best fuel economy.

please do not get a converter built with a stall lower than 1700. you will not be able to put your truck in drive due to it stalling. mine stalls unless it warms up for about 20 min in the driveway when temps are below 30*. it will absolutly SLAM into drive and park which will tear up your trans and differentals. you do not want to do this

The truck already slams into gear. Well i found a hughes with 1800 stall. I guess ill go with that.
