another trans problem to add

[spikesic6sic6]

have a slightly built 4l60e in a 94z today was driving amd it just didnt feel right had to give it more gas from a stop to move it well come to find out after that i got no reverse as well as if i place it into neutral the car cant be pushed any ideas on the problem

[steveo]

wiggle it around near neutral and see if you can get it to roll? misadjustment maybe

[spikesic6sic6]

tried it still nothing idk im fearing the worse

[cahall]

Is the fluid discolored or smell burnt? Does it still move forward? Does it shift through every gear forward? Any unusual noises?

no noises really i left it at my buddies house but idk it felt like i didnt have first gear cuz i know have corvette 1-2 thing but when it shifts from a stand still to the next gear its was to smooth hinting me to somthing wrong fluid looks healthy no burning or anything

[spikesic6sic6]

so yes moves forward but like i said from a dead stop i have to give it alittle bit more gas then normal to move as well as no reverse at all and when in neutral it wont move at all with car on or off

[cahall]

Does it try to move forward in neutral?

Frank

Have you tried putting it manually in first to see if it moves easier from a stop?

[spikesic6sic6]

i think my buddy did when he was messing with it he seems to think i either broke a sprag or somthing inside cuz he said in order toock the trans up in neutral some hard part must have taken a dump inside

[spikesic6sic6]

i didnt really mess with it but i dont think it would work in 1st i if i remember right when he put it in firsy the car went in but made a clunk noise when u gave it alittles gas

In a 4L60E you have 2 things that have to hold for reverse...The reverse input clutch and the low/reverse clutch. If the low/reverse is the problem, you may not have manual low either, however they do use a different seal on the piston. You may have an issue with either of these or in an apply circuit. Conversly, a forward or 3-4 clutch that is staying engaged will also cause a no reverse condition, but should allow the vehicle to move forward with the shifter in neutral.
The park rod in the trans has a mushroomed end that holds the end on. If that comes apart, it will allow the trans to stay in park until it is pulled to a range further away from park, such as O/D or D. This would help explaoin why it can't be pushed in neutral. I've seen this happen on GM FWDs (4T60Es), but rarely in a 4L60E.
There may also be an issue with the rear planetary, but that should cause a noise.
My suggestion is to drop the pan on it. Inspect the park rod and make sure it's disengaging the park dawg. If the pan is full of metal or burnt clutch sediment, you know you'll have to look further.

You'll need to go exploring at this point...

[spikesic6sic6]

oh yay lol so basically before i throw her on the lift if i put it in neutral and im about to push forward and not backward i have the 3-4 clutch locked in? well either way shes coming apart i also talked to circle d here in houston they told me it might be i rolled a sprag cuz my car did shift pretty hard in gear

[spikesic6sic6]

ok pulled the pan today alot of bronze coloring in the fluid and as well as i found a chunk of some sort of band about a half inch wide orange one one side and a friction clutch stuff on the other side :/ time for a rebuild on the rebuild
