I hope so, I'll give it a try and see it cannot hurt at this point. In the meantime, is it causing further damage by not shifting properly? We are aware that it has the problem its just a pain when an automatic is not an automatic.. thanks
thank you very much bp, I have a pint of sea foam in it right now. If I add the lubegard I'm not overdoing it am I? I only have about 100 miles on the sea foam and still doing the same thing so far? I'll have the lubegard today and pour it in. thanks
I thought the same thing about the tps as I've had issues with them before not setting a code so I replaced it with a Napa echlin and no change? I'll do the lubegard and hope it free's up the valve. thank you for your time to reply!
Well, you "threw a TPS" at it, but that doesn't ensure the TPS system is OK. Live-data will save a lot of guessing and parts-swapping.
Still don't want to "splurge" on a $25 ELM327 link? At least check voltages at the TPS (with it connected). Check for the 5V power and that the signal reading is "reasonable" as you move the throttle. If that's OK, then do the same readings back at the PCM connector. Since these readings, with all connectors mated, require either back-probing or a mini BOB, they can be tedious to do reliably. Once the TPS system is thoroughly checked, then you move on to doing the same with all the other sensors; the tedium will continue until you use live-data...
Last pitch: I believe there are several (many?) things that simply can't be checked without live-data. For instance, "gear commanded" or "LP commanded" (to check against a mechanical pressure gauge).
that tps was a last resort to try. I have the elm327 but could not get it to load in either laptop I have and one of them is only a year old?? I will check voltage at the tps but might have my friend at the shop scan it and see what he says. Otherwise if its a stuck valve or solonoid, maybe the lubegard will help. Its an around town car for now so thats part of the problem it doesnt see alot of highway use lately. thanks
He helped me sometime ago and I called him and we couldnt figure the thing out. We did get the program loaded but connecting to the car and reading the info wouldn't work. I see there are so many more versions of the elm now but reading the reviews, they are having the same issues I did. thanks billr!
Well, then, I suggest you post the ELM hardware/software specifics anyway; maybe somebody else can help or we can "collectively" muddle through how to get you live-data. Lack of the live-data will hinder this and any future repair projects. Getting the ELM to work is a bit off-topic, so maybe you should start a new thread for just that?
I've had the lubegard in for around 500 miles and no change on the 1-2 shift. I took it to a friend at a shop and he confirmed code po753 that is was the 1-2 shift solonoid issue. According to his data, it is starting in 1st and skips to third then to OD. But, at around 55mph, you floor it into passing gear it stays in Overdrive? When you come to a complete stop it goes back to first gear and reverse works fine also. The fresh fluid is dark again. The new part is cheap the labor to do the job is 8.5hrs. At this point, I'm tempted to put a reman trans in it do you know of a rebuilder? I've heard of Jasper being good? thanks bp!
there is a company called sw transmission they sell low milaged used transmission with a 1 year parts and labor warranty but i dont know a rebuilder in your area im in south carolina if you was closer id fix it for you.
I wish I knew a person such as yourself that knew how to fix these tranny's. Rebuilts are so expensive I dont know how they sell them when people want to keep their old cars and fix them up. GM made millions of these 4t60's and they want a fortune for a rebuilt unit.
