95 4l60e not shifting past 2nd
Asked by Jeremiah Sep 24, 2017 at 05:45 PM about the 1995 GMC Sierra 1500 K1500 SLE 4WD Extended Cab SB
Question type: Maintenance & Repair
I just bought a used trans from someone it had
189xxx miles on it and it won't shift past 2nd in od.
And when going down the road at about 40 and try
to shift manually in 3rd still nothing just revs up.
Now I had this same problem with the trans I
pulled out of my truck originally. And i assumed it
was my 3-4 clutch pack but the guy I got the used
trans from with 189xxx on it said it shifted fine and
guaranteed it would work. So I what I'm trying to
figure out is if its something other than a clutch
pack. Because I'm having the exact same problem
I had with my old transmission so I wouldn't
imagine they both have bad clutch packs.
Someone please help!!!

Do you think my shifter box could be the problem of cracked?
No the black box on the side of trans that the wires plug into right there at the bell housing
Yes on the side of bell
Thats no where near the exhaust thats right behind glove box underneath the ecm
Alright man I appreciate it I keep you updated
I have had same problem with my 89' silverado. And i have the 700r4 is there any chance it could be same problem?
I have a 95’ k1500 it’s got a 4L60E but apparently it just needed a new oil pump which I replaced but I put it in about 2 months ago but it isn’t shifting out of 1st and the reverse isn’t working well it’s working but it takes a little longer for it to cooperate. Could it be the torque converter or a the solenoids? Any suggestions?
Jeremiah did you figure out the problem? I'm having the same issue as you did
Yea mine keeps blowing the fuse and doesn’t shift right but when I move them and get the fuse to not blow, it shifts perfectly. Anyone have a picture of the harness to replace the old one?
so i think i have the same problem

Speed sensor. My truck had 1st 2nd and reverse. Also the speedometer quit working. Installed new speed sensor and it shifts just like it used to and now the speedometer works. I think it cost roughly $90 give or take.
Did you ever fix the problem?
Bebotheredneckpimp, which speed sensor did you replace?
Having same problem with my 95 GMC suburban......bad timing. It shifted funky for a while and then all of the sudden it wont go into 3rd anymore.

I just had the same problem on my 94 has the 4p60e in it... I replaced the tps sensor throttle position sensor on the throttle body amd then I found a short in the wires from the tail end of the transmission called the vehicle speed sensor... I replaced the end if the plug there like 8 bucks amd followed the 2 wires up till I found the short amd haven't had a problem since

The throttle position sensor The vehicle speed sensor on the transmission The brake light switch on the brake pedal Or short wires are all the things that I have looked for amd know of that could cause this problem... so i replaced all of them amd runs great also my drive shaft where the 2 meet theres a brace or bracket if its bad it will make the tranny shift hard also...
Mine required new clutch pack.
Clutch failures are very common in this transmission under 100K miles.
I have a 1999 silverado and need these same problems, mine does shift into 3rd on the freeway but not with local driving maybe because of not going fast, I did find a wire off on that shifter black box ( I don't know what its called) on the side of tran. I'm going to plug it back in tomorrow my question is could this wire cause this?

Hey! I have a 94 GMC suburban. Trans was leaking so I put in some stop leak. It started shifting hard from 2 to 3. Then it would shift unless I let off gas. Now it won’t shift past 2nd usually and revers won’t move it. Sounds like it goad into gear, but nothing happens. Any ideas??

When you have the pan out ..pull the shift solenoids and clean them too... there is 3 of them.
Reverse..1st and 2nd work perfect.... will not shift to 3rd. Pulled the harness off the tranny to put it into LIMP mode and it starts out in 3rd gear no problem. So 3rd gear is there.. Shift solenoids A and B have to be good else no 1st or 2nd. No errors codes. What could cause no 2nd to 3rd shift?
Hey sorry I'm new but can anyone help me cause I have to same problem but my truck is a 95 Chevy Silverado K-1500 4x4 Extended Cab.... Is there anything I need to do to fix it or is there anything I need to reset or anything along that idea....
