Auto S15 Jap Spec Wont Change Gear Or Go In Reverse

[32vspecII]

hiyall

i have an auto jap spec s15 and it wont change gear properly or drive really at all . It wont go anywhere in reverse , creeps forward in nuetral , goes no where in 1st and is very slow in d or 2nd

we recently took off the TPS to check on a manual aus spec s15 we were having problems with and since then it has done this so i am thinking its the tps

would it have such a severe reaction if it was a tps problem ?

does the auto tps work ok on the manual ? obviously we didnt connect the bottom 3 pin plug . or could we have damaged it by hooking it up to the manual ?

if we disconnect the tps it does the same problems as when its connected , no change would that indicate its dead ?

and finally is the auto s15 tps the same as any other nissans ? i have an auto r33 I could steal if its ok ?
