4R70W + transgo (problem?)

Today I installed a transgo shift kit in my 99 f150 w/ 4R70W transmission. All went well, no problems taking it apart putting it together etc. When driving it it seems as if I can only catch gears if I physically shift it (1-2-D) once in D when im goin about 50-60 and give it gas it sounds like it just revs from 1000-3500 rpm then itll actually move. Is this normal or does anyone have an idea as to whats up/what I did wrong.

Aw hell, I guess I should jump on the wagon.
We sincerely regret to inform you...
No really, that trans-go thing, it was a bad idea. Both of the above are correct. A valve body transplant is likely the only real option at this point.
Sorry to be the bearer of bad news. That kit works fine for some, poorly for most and not at all for many. It is not removable. Its permanent and often fatal.
My condolences.

Yup, the above statements are correct. I used to have a Trans-blow and it worked alright...but having the J-mod is so much better. Follow this link, read everything in the first 3 articles, including the instructions for the shift kit.

I will say this-if you didn't correctly torque your valve body bolts to 90 in-lbs then you can have crossleaks that will cause those symptoms. Recheck the bolts and plan on purchasing a new valve body soon. Then do the previously-mentioned J-mod instead.

Very interesting to come here and see how everyone says that this kit is so bad (not being a smartass). All other info ive read people seem to be all over it but have no supporting info. Just curious but why do you guys keep mentioning a new valve body? Im guessing these kits have a tendency to screw them up?

The Trans-Go kit makes modifications to the VB that cannot be undone. That is why you need a new one.

Sounds like fun. Tomorrow im going to pull it apart again and make sure its not a stuck valve or something and make sure the bolts are torqued right. If it keeps on I guess a new valve body it is . After driving it more after making this post it seems like I only have 1st and 2nd gear. I can physically shift to the both of them but once I shift from 2 - D it makes no difference in rpm/cant feel a shift/nothing. Then when I shift back down to 2nd (same speed/rpm) I get the same results.

Seems like you guys need to go over to ford-trucks.com and show them how pathetic this kit really is.

Do not J-mod a truck valvebody. The plates are not the same. I don't know what holes get modified in the truck valvebody but I can get you a seperator plate for it. At this point you might as well get a car valvebody so you can j-mod it the transgo kit damages the valvebody core.

I took everything apart and put it back together. Still no luck. Although the revving problem isnt as bad.
