Tranny won't go into revers

Hi I'm a new member with a new "to me" truck, any advice on a tranny that sometimes has a hard time going into revers. It's a93 auto 4x4 with 300 + km on it

 

Well it does go into gear just dosint move well when I give it gas or up hill,, almost like ridding the clutch in a manual

 

Same thing happened to my 94. The dog some how knocked it into reverse when I was in the neighborhood. The only way to back up was to put it in 4lo until I had the money to get it rebuilt. Not sure if somethin similar to yours or not though

 

Yea mine backs up fine in 4lo too

 

Reverse clutch pack. Only thing fixing it is an overhaul.

 

oh man that sucks, blew my direct drive on my 89 Toy and it cost me 2 bills to rebuild.
