4L60E Trans Problems Need Opinions

[Hood93z]

I Recently bought a 1994 chevy 4wd it had a 1995 4L60E trans since the 95 model trans was a stand alone year I knew that's why it was acting crazy on me it wouldn't shift it was like it was stuck in 3rd so I traded it off to a buddy for the right 4L60E.

The trans I traded off is doing Perfect in the correct year truck.

Mine on the other hand will not shift out of first when you put it 1 and manually shift to 2 it does fine but nothing past second.. Similar to what the 95 trans was doing in there. Anyone have any thoughts or ideas on what I can do without having to rebuild it..

I can rebuild the trans my self I'd just like to avoid it if possible.

Was it working correctly in the truck you got it from?

 

[Hood93z]

I didn't witness it workin correctly but the guy we got it from says it was I put a filter in it and changed the fluid in it the fluid I pulled looked real didn't smell burnt had a nice red tint to it

 

[Scrufdog]

Well, assuming it was working...

Are you getting any codes? Does it have an adjustable shift or tv cable thats out of adjustment? Are all harnesses securely plugged in?

 

[Hood93z]

It has a 3 inch body lift and the shift cable is stretched not lengthened correctly but it takes park reverse Nutural and drive in the correct places on the column I honestly have paid any attention to the CEL I went back under and checked everything over not real sure what the tv cable is the only I haven't hooked back up is a ground that some da Hooked to the bell housing to the frame with the 95 trans

I'm sorry my truck don't have a shift cable it is a rod

get that ground hooked up and see how it is.

 

[Hood93z]

I'll try it but I was assuming the ground wouldn't work properly hooked to aluminum

I forgot to mention this in my first post but the 4l60e has a heat shield on the side that the harness plugs into well I found an old harness in the truck when I bought it come to find out that was the old harness that the exhaust had melted so they spliced in a new one could they have mixed a wire up?

That, and make sure that the trans fuse is not blown. will produce the same results.

Never thought of a fuse doin that checking that now hooked the ground gonna drive it tommorow and see how she does
