4L60E Drive has no power, must manually shift, ideas?
Hi I have a 1998 blazer 4x4. It has the 4L60E transmission with 99,000 miles on it. I noticed some tranny fluid in the cap of the radiator. So I replaced the radiator did a flush on the cooling system, and I did a pump down on the transmission.
When I was all done I went to drive out of my garage and Reverse seems to be fine while drive is an absolute dog, I have to rev it to 4k before it starts to move. It drove into the garage fine before I did this work.
If I manually shift it 1,2,3, D I can get around (ok). But it still doesn't really feel right that way.
I dropped the pan again and replaced the fluid that was there with 2 containers of Lucas transmission fix, to try and save my tranny while I drive around manually.
I replaced the seal on the filter and made sure it was in tight last night, still doesn't shift right.
Any Ideas would be greatly appreciated.

are you sure its shifting through all 4 gears. alot of times these transmissions go into limp mode which makes the transmission start in 2nd gear. search limp mode on this site, this issue has been brought up a few times. happened to my truck a few months back, nothing like trying to spin big tires while in 2nd gear

So I looked on here and alot of the answers for limp mode also had to do with spedometer problems as well. My spedo works fine my truck is just a dog right now.
I checked it and it seems to never hit 1st gear. I put it in 3 and acts like it is stuck in 3 same with drive, when I put it in 2 I can then manually bring it to 3 when i get going. Never seems to shift while in 2.

There's several 4L60 write ups on DIY. Take a look.
Have the codes pulled. List all of them and dont leave any out. And dont let the AZ guy decide what's important and what's not.

Thanks, I didnt think of looking under DIY, i just did a "search".
I went to autozone (I call them the boneheads), they said that their equipment cannot scan transmissions, so im gunna go to a transmission shop later that does free diagnostics and see if they can fetch all the codes.
Btw petty, im a ford guy too. My 3 season car is a 1996 mustang GT converted to a cobra clone. The blazer just has winter duty. These GM's confuse me =p

We dont have no sweat driving a Chebby no more. The Bowtie v Blue Oval wars is over and done.
Was done the first hick stuck that 'pissing on Blue Oval' decal in the rear window of his rusty old C-10.
BTW: Speaking of embarrassing stuff.. did you check the fuse? IP 'clstr' fuse 11, 10A

Where is that CLSTR fuse? is it in the fuse box in the motor compartment, or somewhere in the interior?
Right now I am out at college while my dad is back home messing with my truck and several other cars, so I cant exactly look for the fuse myself right now.
If I can tell him to look at a certain fuse I can prob distract him from his projects for a minute.

your truck is a little newer then mine but mine was blowing the ign/gau fuse causing it to do this. basically what i found my problem was that the computer was not sending a ground signal to the solenoids to go down to first gear. why? i never figured out. bad computer im guessing but since my truck is strictly offroad and i never had a vss hooked up. i just grounded the solenoids on a relay and got first gear back

Thanks for the location of the IP stuff. I took the cover off and the fuses are fine. However i think the previous owner had a remote starter hooked up cuz the chip is down there Aerostar I think. The wires seem to go everywhere so that might be part of my problem.
Big84 i'll also look into that next time im home, I really do not care if I have a speedo or not, my mustang says im going 150mph in second gear so im used to it
