engine stalling in reverse?

[ScaryFatKidGT]

so i got a new engine and tranny at 170k the engine and tranny having only 70k on them and ever sense in below 10 degree wether it stalls out in reverse unless i give it alot of gas? not in first or second or park only reverse? what is this?

my guess is the tourqe converter its a 4eat

or do u think a tranny flush could help? sea foam?

[ScaryFatKidGT]

help any one?

Torque converter is my initial reacting, but the fact it only happens on cold days is kind of wierd, also that it is only reverse is interesting. Once you are into reverse can you idle? Does it depend whether the car is warmed up or anytime it is under 10 degrees?

[ScaryFatKidGT]

it is only in reverse it will idle fine in nutral, park or first gear

once its warmed up its ok its when its cold out and i just start it and try to back up it stalls out and kills the only way i can reverse, when it acts up, is to gas it backwards and then to quick switch it to drive before it kills

but yea once its warmed up its ok

its almost exactly what happened when i blew my HG but its only in reverse and only when the engines cold and when its cold outside

Ill look around today to see if I can find any info... Back into parking spaces? the car will be warm by the time you park.

selector switch is maybe on the fritz or out of adjustment?

[ScaryFatKidGT]

yea if i go to work i back in but like going to someones house or something i just kinda pull in to the drive way and yea

the selector switch?

mhhh also sometimes when i wash my car with undercarage was it goes on the fritz like going in and out of gear but i just did that to day and it was fine so idk

[decke48]

slector switch is what tell the TCU what gear its in. it sits on the outside of the tranny where the shifter cable connects to the transmission

[ScaryFatKidGT]

could water get on that and make it mess up?

and is it replaceable

[decke48]

could be. and yes you can replace them

[ScaryFatKidGT]

do u have to pull the tranny?

[decke48]

no you just need to remove the cable of the pivot. some bolt. and adjust the new one
