OK guys, I know you all have beat the "no reverse" issue to death, but please don;t beat me. :spank: I've searched alot of the posts dealing with this problem, but havn't found the exact symptoms mine has. Myabe someone can enlighten me.
97 Suburban 4x4. Rebuilt tranny has 16,000 miles on it. Bought it through an internet advertising "builder". Came with a 1 yr unlimited milage warranty. It's been a yr and a half. Anyway, on startup after sitting overnight, it would take 3 or 4 seconds for it to go into reverse. Then it progressed to not going into reverse, or I'd have to jiggle the shifter and then it MIGHT go into reverse. Now, it won't do even that. Drive is on a slight grade, so I'll roll out of driveway, in reverse, but not actually engaged in reverse, drive around for awhile, and it MIGHT shift into reverse after its up to operating temp. Sometimes, after it does go into reverse, it might shudder as I gently backup, but sometimes, it'll back up normally, even to the point that I can hold on the brake and gas it easily, and I can tell that it is FIRMLY in reverse with no slipping to speak of. I talked to the rebuilder and he's thinking cracked low/reverse cluth piston....due to it behaving more normal after it's up to temp. The fact that I can jiggle the shifter and that sometimes helps makes me wonder if it could be in the boost valve in the valve body.
All forward gears seem to be just fine....I can watch the rpm drop at each shift. Not sure of the engine braking in manual 1st gear. I can take it up to about 20 mph in manual 1 and let off and it doesn;t "engine brake" until it has gradually slowed to about 15 mph...then it engine brakes noticably. Oh, I have not put a pressure gauge on it yet, so I don;t know what line pressures are. Any ideas or suggestions?
Thanks for the patience with the newbie here.
