When I decelerate in 3rd gear the tranny growls I have another trans I got with the truck but unsure of what year it is. I have it completely disassembled. I want to get a repair kit but want to make sure I order the right one. In Motors Manual it say 53 and newer have 24 needle bearings. I found more than that in the trans so I know someone was in there before. Have 50 of the small long ones. The trans is marked 5 GM 591615 It has C11 verticle above that. The pad next to the side cover is marked JO 96542. 4 bolt side cover and have torque tube. Will the later kits fit or is there different bearings for the 3 speed with the tail shaft..Also what is going on with the existing trans. Shifts great and the synchros work. I either let off real slow or push the clutch in. The trans in the truck is marked 3 GM 59615. Thanks for any help you can supply. | | | | | Joined: Nov 2012 Posts: 41 Wrench Fetcher | | Wrench Fetcher Joined: Nov 2012 Posts: 41 | | | | | | Joined: Feb 2004 Posts: 29,771 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,771 | Are you sure the growl is coming from the transmission? The symptom you're describing is usually a sign of a failing pinion bearing in the rear end. It starts out as a growl on deceleration, and will eventually start making noise on a pull as the bearings get into worse condition. There will be little or no noise on a "float" where you're neither pulling or coasting.

It rocks back and forth. Must of had old grease or rust in it and by driving it itflushed it out. Great call!
