"Is this normal" questions concerning tranny and stall I got the stall and new tranny in and I have a couple questions. As I slowly accelerate it is like I get no TC lockup at all until about 40 and it catches and throws down to about 1200RPM. Is this normal? I'm not sure what to think about that yet. It sure makes my exhaust louder which is cool for days when I jsut really want to make noise....
Also, I am not getting good engine braking. It doesn't seem to use lower gears to slow the truck, even with the brakes on pretty well.
Are these things a tuning issue, normal, tranny issue, stall issue? Help...?
It shifts well though.... the tranny feels crisp on the higher throttle shifts. And talk about no traction.... I just barely get into it and I spin,

You went from a stock converter to over 3,000, so it might take some getting used to. Once the Torque Converter clutch locks up, then its no different than a stock converter locked up, because zero RPM of slip is zero RPM, regardless of converter.
Consider programming out the Pulse Width Modulation for the converter too. That "feature" maintains a tiny amount of slip in the converter to smooth out engine pulses but it relies on the carbon-fibre clutch materials in the stock converter for longevity. Removing PWM through programming or with valvebody modification will make lockup feel solid and precise like a 700R4.

Thanks guys!
Alright... check this out. I've contacted the builder and I'm sure Bernard will help me find the fix.... I have a leak that makes 0 sense.
The transmission is leaking from the rear, but it is NOT from the rear seal. I am positive of it. It is dry around there. But, I can see it dripping off the front U-joints. How is this possible. I talked t a guy @ the parts store who seemed to know what he was saying,,, and I basically asked "Is it possible that an internal seal isn't right and it let fluid flow into the yoke, and slip out the hole @ the end?" He said that that wasn't possible, and it has to be the rear seal. I bought it, went under to change it and the same as last night, the seal was bone dry. It is in fine.... I see it dripping from a ujoint.
Any help here? Thanks in advance.
I'm just ready to drive my truck.

There is a hole in the end of the yoke for movement pressure equalization.
If the splines are clean and in good shape the fluid should normally stay slung around the circumference.
There is a slipyoke grease that should be in there. That alone should prevent the fluid from flowing past. Maybe it needs to be cleaned and regreased.
In a problematic situation the hole can be plugged with rtv.

What does it damage/ create potential for damage if I seal that hole.
I was at work while my dad put the driveshaft in and he didn't use any grease I don't think. Is this special grease or can if be general purpose grease?

My dad had some gear grease. It was pretty heavy. I just put it on the splines of the yoke as far as my middle finder could reach and slid it into the tranny... is that right?
I really don't see how that fixes it. But hopefully it will. Thansk for the help man!
