everything was working fine.. i decided to launch it in 4wd so i stalled it when i let off it left really slow.. i didnt bother thinking about it.. came to a red light and and took off but it took off in second.. kept going but it wouldnt shift into 3rd.. slowed down dropped it to 1st and it down shfted.. then put it in second and it shifted fine.. popped it into 3rd and it swouldnt shift.. its stuck in 2nd.. what can it be? something in the valve body? it doesnt shift into 3rd at all. im letting the truck cool off but the transmission was cold i had just turned it on when i did that.. any help will help.. thanks. btw transmission was built a couple months ago.. its on a hd2 shift kit and all the other goodies..

 

Does it shift into 3rd if u are 2wd? Is this a 60e or 80e? Sounds like 3-4 clutch pack is out. My 80e gave out on me when I tried launching my at the track the other day it was doing the same thing.

 

no it doesnt go into 3rd at all.. last time i lost 3rd it would shift but just rev.. it feels like i hold 2nd.. it just stays in 2nd.. tkes off in 2nd and doesnt shift.. like it its stuck..

 

Scanned it for codes???? Sounds like it could be solenoid related

 

no i havent scanned it.. i dont have the software at this time and yea i was thinking the same thing.. will a scan tool detect a solenoid problem? thanks for ur help..

 

Isn't 2nd gear only a basic mode of operation, like a protection mode? They will do that if you unplug the transmission's main connector.

 

just spoke with my cousin the one who built my transmission.. same thing he said.. told me to check connections and fuses.. im about to do that rt now..

 

You're close!

Actually the limp in mode you're referring to will allow for 3rd gear starts, manual 2nd and no 1st or 4th and no converter lock up.

Ok so last night I went ahead a unplugged battery checked all my fuses and unplugged the transmission and then put everything back in and this morning everything worked again. Thanks alot I guess it was an electrical issue.

 

Was it a fuse? Or do u know which conection it was? Mine is doing the same thing! I had it rebuilt and still wont go into 3rd or 4th. It didnt even need a rebuild so I wasted a ton of money for nothing. Already lol
