Does anyone have any new info to add?
Has anyone experienced any new leaks or problems?
Just curious. Making plans on doing this project and would like to know...

 

I would probably go 2 1/2 or 3 turns on the pressure turn up if i did it again. Transmission feels much stronger and pulls harder. I'm really glad i did this right before the dyno. No leaks or anything on mine. Just follow this great write up and you'll be fine.

 

800 mile road trip and feels great. I love how I don't rev over 2,000rpm on every hill. I CAN get it too go to over 2,000 on hills if I gun it, but not with moderate acceleration. I couldn't even HOLD my speed up hills without it slipping before.

I would give a hair more turns out on the pressure as well. I'll be throwing a gauge on soon to see how much more I want soon. I'm also going to be turning the blue threadlocked one 1 more turn. I was warned NOT to go more than 2 turns total, and someone else gave a measurement. i'm assuming something can go bad! My low throttle shifting is definately at a higher RPM now like I wanted. I just assume it will be worse again after I do my 366 spring...

 

Well, just got done doing this one.

After it all I can say the trans does shift super smooth now.

We'll see what the future holds for it.

Thanks again for the great write-up!

 

I'll have to give it a go this summer when I can sneak into the shop. Right now I have about 500RPM slop holding 55mph. Next would be valve body then torque converter. But that expense will have to wait until my other truck gets a tranny.

 

I'm a solid 1800-1850 at 55mph now. I used to shoot over 2100 or so pulling hills, now it's steady unless I really romp on it or something, but that's probably mostly torque converter slip at that point. I don't know what kind of spring you guys are having up there in Alaska this year, but it's a doable task laying on a piece of cardboard on a calm day with little wind. Probably 1-2 hours.

 

when is this goin in the sticky???

 

Is this all on the stock converter? Would you still change it if it is?

 

Yes it's with the TC that came in the truck when I bought it from the State of South Carolina.... so I assume stock or stock type replacement.

Yes, I'll be putting a Goerend in. I have a little more torque converter slip at lower RPM's since it's not as efficient untill you get around the 2000rpm level or so (normal). Most my roads to work are 40-45mph. I'm also getting it since I have a US Gear aux overdrive that will be going behind my 727, and the lower stall will be nice so it doesn't just slip back up to a higher rpm again.

Note: Adjusting your bands is supposed to be standard maintenance ANYWAY, so if you are uncomfortable turning anything else, you should at least do the bands.

I'm thinking the shift adjustment is very benificial for guys that have the 3200 rpm spring in since it delays shifts at low throttle input (which is common with the 3200 spring). I will say again that I was thoroughly warned NOT to turn it in more than 2 turns. Someone in the this thread gave a measurement too... I assume something can go very wrong. I did 1 turn and I'll probably do another when I get into it again since turning up the fuel made so the truck goes much better with low throttle input.

 

Looks like your running about a 100RPM higher than me. What is your axle ratio?

 

1850rpm is 1000rpm more than you at 55mph? I have 3.07's behind a 3 speed 727 with no overdrive. Final gearing is somewhere between a 4.10 and a 3.54 with an OD truck.

 

It's been there since the day it was posted.

 

woops i guess i didn't see it. thanks

 

I'm running 1750ish @ 55 on level ground in OD on 3.54s and standard tires. So I may see a drop in RPM @55 after the adjustments.

 

Whoops, thought you said 1,000 rpm's more. I see now it was 100. I bet you'll drop a little more too. Then again, my tach may not be 100% accurate. Its the type that straps to my altenator and you have to set the tach at a known RPM.... I just held it to the floor in neutral (completely stock truck at the time) and set my tach at 2700rpm. When I let off the throttle it settled at 700rpm which seemed about right. This method may or may not be the most accurate way, so I may be turning a little faster or something.
