what should i do with the 727

[dodgeman1990.5]

my 2wd truck has a 727 and 3.07 rear end and the thing is screaming just to do 60 im trying to decide if i should try and find a higher geared rear end(i dont even know if they make one) or put a gv under overdrive in or do a trans swap???????????????????

[dazedandconfused]

What size tires are you running? Are you sure its still 3.07 geared and sure the trans isn't staying In 2nd? My 89 powered Chevy would run 97 before it ran out of rpm and cruise at 70 no problem. That was with 235/85/16 tires.

it is shifting into all three gears and it dosnt slip i have 235/85R16 the tag on the diff cover said 3.07 but i didnt believe it so i pulled it off and counted the teeth and put them into a converter thing i found on some jeep fourm and it confermed 3.07

[dazedandconfused]

Well 3.07 is as high as was ever made and no longer available. Do you have a tach in the truck? Only other thing i can think of is a weak trans with a wore out stock converter that isn't putting the power down just letting the motor scream.

that is a posibility the truch has over 230,000 on it i have only had it for under a year so im not sure what was done with it. i know it used to haul a 5th wheel camper all the time and it dose have one of them under the bed trans coolers along with one in the grill

[dazedandconfused]

Hows the fluid look in it? If its still red and no metal in it you could throw in a shift kit, adjust the bands and a more efficient converter. Like i said with a fresh stock 727 i could cruise 70 all day and top out at 97 in a 7000pound crew cab chevy.

It will make a lot of racket at 60 even if everything is working right. I briefly had an overdrive transmission in my truck and the noise reduction was amazing.

For what it's worth, I have 250k+ on mine and the original owner doesn't recall ever having transmission work done to it. He and I have pulled goosenecks loaded a tad heavy a time to two

Like dazedandconfused, I can exceed my 85 mph speedometer without much effort

Od trans swap is only way to fly

well this truck is too nice to drive up here in new england winter so i guess i will pull the trans and rebuild it and put in a good TQ. have any of you ever rebuilt a 727 i found a 20 part step by step video on youtube. Any ideas on a decent TQ and rebuild kit that wont give my piggy bank the runs?

[dazedandconfused]

Goerend or spec rite for converter.

thanks for that i actuly emailed them with what i have and asked them if they could put a list of all the parts i would need. i just went and picked up my uncles boat and it dose seem like it takes a lot of rpms to get it to move.

well to rebuild the trans is gonna be about $900 my piggy bank got the exploding runs

I'm running a Specrite converter. Along with a Patc rebuild kit. I added some extra stuff to the rebuild kit and it brought the price up to $700. Before that it was at around $500. The converter will add another $700 at least.

my rebuild kit is $222, TQ $350ish, front band $40, the shiping is almost $100, $175 core and then all the tranny sause

[dazedandconfused]

Buy a good convertor from specrite, goerend or suncoast.
