[quote=&quot;John Wiggins&quot;:31q99z89]I have Oliver 880.   It seems like it is catching on something when going up hill in 1st, 2nd,  5th and  low reverse.   Last year I put in low range input shaft bushing and some bearings on top.    Have not had a load on it , but have done  a little bush hoging around barns,   seems to catch going up hill.   Did the same before putting bushing in it.   Has helical gear transmission and power booster.   power booster works fine.[/quote:31q99z89]

It has been about a year since I worked on 880.   The catching is like you touch the brake for a split second.   I don"t think I ever had the power booster in low range when i noticed the problem.   By the way I have had this 880 since 1995 , I have another 880 I have had since 1982.   No transmission problems with it.   Both Helical and both have power booster.
