Thread: Replaced forward clutch band, now stuck in drive.

Hi,

I replaced my broken forward clutch band (4T65E, in car replacement), took it for a drive and everything seemed to work great. I could hear it shifting through all of the gears, etc. I went to test manual shifting and the lever would not go to 3rd. Then realized it wouldn't go into neutral or anything else. Couldn't find a cliff to drive it off of, so just drove home depressed.

Popped the shifter cable off and it moves fine, but the transmission gear selector is locked up hard. Took the whole thing back apart (up to the trans side cover) and it looks like there is a long rod that goes from the selector mechanism clear to the back of the transmission. I didn't remove this rod and don't remember doing anything with it, but it seems to be the problem. At least from what I can tell so far. I'm fine with taking everything back apart, but I don't know what I did wrong, so I'm sure I would make the same mistake again. Any ideas what is causing this problem, or what I missed?

Sorry to bug everyone with such a vague question. It's pretty clear I shouldn't have gotten into this repair, but I'm kind of stuck now.

Thanks

I don't believe so, BUT, it is relieved on one side. This is allow the shift linkage to pass through and sit flush. So, not directional per se, but it does only go one way. I suppose if put in incorrectly, it could cause it to bind in the bore.

Also, if one of the valve cover gaskets got misaligned could it cause a problem like this?

Not likely. You would see a problem with function, like not shifting or something like that.

Kinda what I was leaning towards.

How far into the bore is that spring suppose to go under normal operation?

It goes in pretty far when you manually shift 3-2-1.

Awesome. Glad you got it fixed.

Uh..... brandon help me understand what was incorrect here. Rod he mentioned sounded like park prawn.

Yeah. You know how the manual valve has that half cut/relief clearance to accept the manual valve link...

My assumption was that he put the link on the unrelieved side of the valve. Which caused it to stick out beyond the major diameter of the valve bore. So, all was well in P,R,N,D, but when he went to jam it into D3 (and force the manual valve deeper into the bore) the link and link retainer crashed into the channel plate.

I was. Thanks for the clarification. Somehow I hadn't thought about that one

Hindsight is always so clear lol. We've all made mistakes and thank you for making sure yours is clear and easy for the guy that does it next. I have tons of write ups..because I wanted others to learn as I had.
