93 4l60e with crazy reverse symptoms

[PJ Martin]

I have a 93 Silverado. 5.7 4l60e 2wd rcsb. My truck goes fine in forward gears. Shifts great. Works fine when I shift it manually or put it in drive. My problem is when I put it in reverse. When it is cold, it does not seem to do anything. Kinda acts like it is slipping. Once the trans is warm, it will go in reverse most all the time. The fluid looks fine and it is full.

There is a ticking noise that is coming from the transmission some where. I haven't pin pointed it yet. Sounds like a card on bicycle spokes. The ticking is louder when the trans is cold, and nearly goes away when warm, but I still slightly hear it. It makes me think that it has something to do with the no reverse.

Any ideas? I just bought the truck a month ago and really love it, I just want to get the reverse fixed.

Thanks
PJ

Is it a tinny type of sound? If so your flex plate is probably cracked

It's a ticking sound. Kinda sounds like a lifter ticking but I know that it is not a lifter.

broken sunshell or worn out low/reverse clutches.

Bad lip seal can cause the slow/no reverse also. Not sure about the noise. Would suggest checking the flexplate first. Broken sunshell will cause no 2nd, 4th, or reverse, also broken rear planetary gears will have the same effect. (been there and done that)

I would agree... Most likely the low/rev seals are hard. When pressure is leaking around the hard seals they will make a noise. You may try and service the transmission and add a bottle of Lucas. I have seen that help sometimes. The seals will get softer the warmer it gets.
