no 4th, taking off in second, and bogging

[black7.3powerstroke]

my 2000 7.3 is having trans problems again. it was just rebuilt not long ago and had 2 converters since then. no programmer or power adders. the reverse is hesitant if it decides to have reverse at all, sometimes it takes off in 2nd then drops to 1st but not everytime, sometimes it goes into 4th but sometimes not. ive got 3 codes p0733, p0782, and p1783. please help. **i put a HD converter in it.

It could be the solenoid packs. Thats where I would start, could be anything like a little piece of dirt or something in the VB. why Did the other two converters fail?

Well once I got a bad converter and then my programmer eat two up

After the last converter went out i took the programmer off. I think that there is something in the paraameters that is messed up. I called the guy who built my Trans and he came to my shop and drove it and told me the gears were there it was just slipping in and out. He put 2 quarts of fluid in it and it is better. It now has all gears but reverse didn't change. And it hangs in 2nd till like 2500 even with light throttle. It's got a new solenoid body. And also a TransGo reprogramming kit. reverse has always been a little hesitant since the build. But not this bad. He told me it was the reprogramming kit causing this.

Here's the whole Trans story...

I bought the truck in the spring of 2011 and put a superchips 1705 max micro tuner on it. Then in July I got a set of 20x12s with 36x15.50s and 2days later the tranny went out. He said that everything in the Trans was shot. Nothing but the valve body and the case were reusable. So I paid 18xx.xx to have it built, new dacco converter, TransGo kit, and rear main seal. Drove it for a day and a half and the converter went out. Took it back and he put a new converter and another new pump in it(had scars in it). Dover it for about 2 months and the case busted around the bell housing. So I got a used Trans and took it back to the
