Yes it will matter a hell of a lot!! trans cooler hose is made for pressure brake booster hose is made for vacuum, the trans cooler hose is reenforced to stop it from ballooning and the booster vacuum hose is re reenforced to stop it collapsing. See the difference ?? Better replace it to the correct hose for your's and your family's safety.

Sorry if i come across rudely.
