3.4 swap.. BIG problem
I have a 1994 toyota pickup 3.0 auto trans that I have recently replaced with a 1998 3.4 out of a Tacoma. I used the ORS wiring harness and everything seemed fine. I loaded it up on the trailer to take t to the exhaust shop and it ran just fine and went into reverse with no problems. 550 dollars worth of exhaust work and I was ready to drive my freshly swapped pickup back home. I put it in drive and it absolutely refuses to go over 10 mph and will not shift what so ever. I'm not sure if it's stuck in 1st or if it's locked in a higher gear. But the harder you hit the gas it'll just sound like it's put itself in neutral.. I've checked everything on the transmission and from my knowledge it's hooked up right? Has anyone ever had or heard of this happening or have any clue of what's going on and how to fix it?

Didn't you have another thread about this?
Did you pull the codes from the transmission control?
If you are the same guy with the speedo signal disconnected. Yes you need the speed signal to the transmission computer or it doesn't know when to shift!

My brother may have posted about it but I'm not entirely sure. If so I apologise. But the speed sensor was disconnected at first but it's still doing the same thing. And I've hooked up the scanner and it's giving no codes at all when I know it should be. I ran headers and straight pipes. No 02 sensors or anything yet. And it's saying everything is fine. I'm just seeing if anyone knows anything until mike gets back from his break and then I was gonna call him. But it's still something I'd like to figure out as quickly as I can. If I need to I can post pictures of what sensors are hooked up where
