hi i just installed new trans and there is no reverse or nuetral gear when its in reverse car goes forward and same for nuetral any ideas?

88supramki

auto? Manual? what car? did you put the correct trans in?

jeremysc40

it a auto and i replaced it with another auto trans 93 sc 400

jeremysc40

the trans's where both the same but one had a cable to control throttle vale pressure and the other had a solenoid to control TVP so no it wont ****f into reverse and or nuetral my question is that are the valve bodies the same beside the TVP acuation system or are they totally different?

jeremysc40

sorry trans's are both 30-40le and ones electronis TVP and the old blown trans is Cable TVP

what year is your car? and what year is the replacement trans from?

jeremysc40

not sure the year of the new trans but the old one is a 93
where do i foind the year on the new trans

just from what you're saying it sounds like you got a replacement trans from a newer SC4 that uses the ECU to handle the shifting. Which would indicate that you might need the newer ecu.

I'm not 100% but it sounds like your trans is not compatible with your current ecu

so this is what i did i had to remove the valve body from the old trans and installed it on the new trans assuming there are the same besides the TVP systems. so i installed the old V/B on the new trans and now it wont shift into reverse and neutral and when i put the shift lever in either one of those to gears im still able to move foward and even in nuetral i can still move foward ive checked all the linkages and park/nuetral control switch and they are all in the correct location so im wondering if the valve bodies are diiferent? and if they are the same what can be my options for fixing this think

jeremysc40

i was thinking it could be that but im using the old valve body on the new trans and would this still make a difference plus the shifting control is being control by cable in my car so thats why i had to swap valve bodies. so basically im F*** and have to get another trans that compatible

on the surface it seems like u simply installed the wrong trans.

Dont dig yourself in deeper by swapping ecu's and messing with other areas.

Just bite the bullet and swap it out again this time with the exact same tranny.

jeremysc40

so basically swapping out valve bodies didnt do anything? and when i swapped out the valve body i also swapped all the sensors also so this still wouldnt make it work?

In short...no. your best bet is to find the exact same transmission that you need for your car and change that one out.

Where did you get the current replacement one?

jeremysc40

from a local junk yard but they wont take it back after it was installed because they said it must of been something i did to the trans so im F'd both was just my luck

I dont like to condone dishonesty or conning but junkyards in my area arent very customer friendly or courteous either so I dont feel bad really.

You should of told them there were some stripped bolts or the internals were messed up somehow, technically you can still get your money back but you have to be very firm and forward.

Belive me if you call them twenty times a day they will eventually give u your money back.

Stick to your guns because for all we know they gave you a defective tranny.
