More Tranny Questions

[tahoe44]

Ok guys I changed the filter on the 93 LT and the tranny is feeling better except for 1st gear, it is winding out and when i let up on the gas then it shifts and from there no problem. Any suggestions?
And can anyone tell me what the normal running temperature of this truck should be.

I hope that this helps you

Shifting seems delayed
Description:
While you are driving, the transmission stays in one gear much longer than it did before. The shifting process feels normal, but takes too long. The problem is noticeable because you can hear the engine more as it runs faster before the transmission changes gear.
Possible reasons:

* The throttle linkage is out of adjustment or damaged
* There is an internal problem in the transmission
* There is a problem with the engine
* There is a problem with the electrical controls for the transmission
* The transmission filter is clogged
* The vacuum modulator on the transmission is faulty or the vacuum line is damaged


I stole the info from the AAMCO transmission web site.
They seem to have a decent troubleshooting guide



My temp is in metric so I can't help you there

thanks OBP I will check it out.

180 degrees is a normal operating temp for your blazer. Like OBP said, change fliud and filter first, if that doesn't fix it, More than likely, it's going to be a internal transmission problem. Possibly 1 or more shift solenoids, on the valve body. Or valve body and or spacer plate could be worn.They are not hard to check or replace if needed. It really depends on how mechanical you are. You can certainly get very good advice in this forum. If you don't know what you are looking for or how to do it yourself, these guys in here can realy help. Just take time to put it in your thread, and try to be as specific as you can be. Also please be patient in waiting for a response, because many of us work and can answer your questions right away. But you will get their comments and suggestion when they enter the forum and have time to reply. Keep us informed on your progress.

thanks SC yea i am mechanical i just need to know what to look for, what to change, etc. I changed the filter and fluid and I am still getting the winding out in first gear.

[laxman21]

Are there bubbles in the fluid when you pull the dipstick?

[corning_d3]

You may have a sticking valve. From what I've seen, these transmissions don't have the best valvebody. Try some of this
I'm not fond of additives, but this stuff will free up sticking valves!

[tahoe44]

thanks LAX i am not sure but i will check today, thanks Corning at this point i will try anything do you realy think the additive can work, It cant hurt right?

[Southern Comfort]

I have an ATSG manual I can take picture of the valve body for you and email them. I don't have a scanner, but I do have a digital camera. If you want me to email them to you, I will. I'll need you addy. Mine is

Is this a electronic transmission? If its a W engine (CPI) then most likely a electronic, take a look at the TPS values. As you open the throttle, the TPS values should increase evenly up to the maximum. The computer uses the TPS value (along with other sensors such as MAP, Coolant Sensor, Speed Sensor) to command shift points. If the value(s) are erratic or to high/low then the shift points will be altered. Also it would be a good idea to take a look at the MAP sensor, and coolant sensor outputs. Are you getting TCC lock-up?

[Southern Comfort]

Yes you are correct on all of the things to check. Tahoe44 is the one who is having tranny problems. I appreciate you posting your message. If you don't mind, can you send that post to him. We all appreciate you taking your time to help others that are having these sort of problems.
Thanks
SC

[blazes9395]

What do you mean send it to him? It is intended to him.

[Southern Comfort]

Oh yea I see it now. It came to me in an email. I thought is was sent to me to view. I'm sorry for the mistake.
Thanks
SC

Every transmission i poured it in started working again. But this will only work if you have sticking valves n such.

[tahoe44]

SC I will take those pics thanks [email protected] Blaze it is a W engine and it is electronic but TPS values, TCC lock-up all i heard was Charlie Browns teacher....lol I need you to explain what they are and how to check them-- be patient boys i am a newbie....lol
