1995 P/F Reverse prob

Hello everyone my reverse went out on my PF SE 4x4 and the transmission is only a litle over a year from being rebuilt. I was told that the reverse drum and another part are not holding preasure so they need to be replaced I tried to look up the reverse drum on the internet and could not find it any where. The shop want to Charge me $1102.00 to do the job 400.00 in parts and the rest is for labor and fluid. does this sound about right. pls let me know.

Thanks

That sounds about right...these complicated automatics are very touchy and tough to diagnose, much less rebuild. I'm sorry for your loss. ;)
