95 was a 1yr only, wrong tranmission? Usually, rebuilding the 95 is the only opiton.
My tranny fluid looks to be pretty over filled, will that cause any certain problems?
#28 happened to me yesterday.......I ONLY got 205K out of the thing.......oh well. I guess the mighty 4.3 was too much.
would you know what would cause my trans to crack right between the pan and the transfer case adapter? this is the third one its happened to. last one was fixed under warranty but this one is just out..... just my luck... 1997 gmc k1500 5.7 233000 miles bone stock, no off roading , no towing or hauling , just a ride around truck. greatful for any help!!!
picture was after i tried to jb weld the crack to slow the leak down
Has the truck been wrecked? When you unbolt the rear transmission mount, does it push sideways? In other words, do the engine and transmission sit in opposition to the mount?
no wrecks.... i have not taken the tranny out myself. put i could do that this afternoon if the rain stops and see..... so unbolt the mount from the crossmember and see if it wants to go to one side or another naturally?
That would be what I would check first. If i remember right, there's a single stud from the mount that goes into the crossmember, which would keep it from sliding, you may want to take the bolts from the mount to the transmission out. It's a bit of work for a shot in the dark, but you're dealing with a non-standard problem, and I don't have a better suggestion.
I thought I had # 28 going on..
Sooo , it wasnt that? i changed the fluid and filter , no difference.....4 days later , i move the truck into the shop and its not under load anymore in park and shifts into all gears f/r no prob.....
Drives and shifts better than it ever has. WTF?
Oh well , i have a good used 1994 2wd 4l60e on the shelf now that i payed $700 for.
I would like some help. I have a 1999 Chevy Silverado 1500 Z71, have replaced the engine and Transmission (4l60e) with Factory Re-manufactured units, my truck after warming up (20-30Minutes of driving) will shift out of overdrive, sometimes it shifts back in, but eventually stays out until cool down. I took it to Eagle Transmission to be checked out and was told that the Transmission checked out good and that the 4l60e is electronically controlled and to take it to a automotive electrical expert to find any electrical issues. I have read on this forum of others having similar to the same issue. Could it be a bad ECM? or what should I look for? Thanks,
shifts out of OD and into 3rd? do you get a check engine light with 6-7 tranny codes? do you loose your speedo and PRNDL gear indicator selector light?
if so it's probably your ignition switch but could also be as simple as the big round tranny plug is not fully connected. Pin E on the tranny plug is the only 12V+ connection and it should read the exact same voltage as the battery. if it drops for whatever reason the ecm puts the truck into limp mode which is the symptoms above. could also be a bad fuse or the pink 12V+ wire fron the ignition switch, to the fuse panel and down to the tranny plug. the wiring however is probably fine.
and if the problem is electrical in nature you will have a code with the exception of a failed or failing throttle position sensor. the tps is easily checked with an obd2 reader in graph form, this could be your problem as well as the ecm correlates the vehicles speed with the tps to dictate when to shift.
