ok, i get off work and head home. i get home and i decided im going to go into town and spray off my ty, then go and work on the 64.

so i head into town and my ty is running awesome. im goign down the main drag , heading towards the car wash. im in the wrong lane, so i cant get over to get to the car wash, lots of traffic. so i decide ill just turn around. so i hit an littlew back road so i can turn around and i come to a stop sign.

i turn onto the road and i notice my try is reving a lot more then usual. my ty decides it doesnt want to shift out of 1st. :roll:

so im like :rant:, i need to get home. so i go all these back raods so i can avoid traffic.

everytime i come to a stop. then take off my ty acts like normal then i doesnt shift out of 1st. and after about 15mph is seems like its slipping. like it just revs and wont go anywhere.

so im limping the ty home. i decide im going to head to my boss's house which is nearby. i get on this road the has a big hill. and im like :squint: im not going to make it up the hill. but i go for it anyway.

i get about halfway up then, my ty shifts in OD. so im like sweet. i can go now. i get up the hill and to the end of the road.

i go to turn right at the stop sign, nobody is coming and and imlike 1000ft from my bosses house. so i turn onto the street getting ready to limp it the restof the way there.

then the ty decides to shift into 2nd, 3rd, and OD now. ilke nothing ever happened. :squint: is this possible?

i get to my booses house work on the 64. then i decide to drive the ty back home.

it shifts fine like nothing happened.


soim like what the hell? anyone have any suggestions? is it someting electrical? im afraid to drive it anywhere.

i did check my tranny fluid and it was full also.

Well, start with the basics: Check fluid level and condition, TV cable adjustment, etc. Hopefully the clutches arent damaged. Could be a gov. gear as well.

Re: my transmission is acting really weird

Sorry to say but your transmissions days are probably numbered :(. I had the exact same thing happen to me with my first 700-R4 except getting stuck in first was the result of trying AWD doughnuts... And this was over 100 miles from home no less. I was cruising with a bunch of fellow sytyers and everyone took off in front of me. I didn't have any other gears other than first. At first they didn't realize that I was broken and took off without me. They did come back once they realized that I was missing. We took the back roads to my bud's house since I couldn't go much over 30 MPH. About 20 minutes into the trip, we had to go down a big hill. While I was coasting down the hill, it shifted into OD and everything was fine until a few months later when it finally grenaded two weeks before the '02 NATS.

I had put a deep TCI transmission pan about a month before the doughnut incident and noticed what appeared to be the ends of busted springs in the bottom of the pan. I got all the busted parts back from that transmission and I the sprag was torn into two. The spring ends came from one of the spring retainers. I had also stripped all the teeth out of the rear planetary carrier. The guy at the transmission shop said he had never seen that done before and asked what the transmission was out of and I told him "just an S10"

If you are lucky, it may simply be a valve got stuck. However, if you are high mileage with an original tansmission, be prepared to shell out $2K plus to fix it :(.

Don't feel too bad, I'm at that mileage right now and I'm on my third 700-R4. After #2 went, my truck sat for over two years before I got it back on the road. Sucks paying $396.52 a month on something that you can't even drive...

When this one goes, I'm done with 700-R4's:

Re: my transmission is acting really weird

The 4L80 is a stout transmission that can take Diesel abuse. its by far the upgrade and its also a 4 spd with OD and the swap in is about 4-5K$ considering the 80 is an electrical transmission, whch needs somekind of computer to operate it.
