p1087 caused by low tire pressure?
Is it possible for low tire pressure to cause the p1087 code?
UNNECESSARY DETAILS: I had been throwing a p1087 cose for a while and it was causing all it's normal problems: no lock-up, hard shifts. It only occured after a while driving locked-up in 4th gear.
Over the weekend I filled up my tires, which were extremely low, >20psi, and headed on a 50 mile highway trip to the airport, expecting the problem to arise about 1/4 of the way. Well it seems the problem is gone, no SES light noshifting trouble, no lock-up problems. Is it possible for low tire pressure to cause the p1087 code, and filling my tires to resolve it?
I had been preparing to install a shift kit to resolve the problem, but I have had no time to install it with my loaded schedual. Is there any other reall reason to install it, or should I sell it to get my money back now?

Well in and of itself no but here how it could contribute , If your converter clutch is weak burned or poorly applied from low preasure , The tires being low do increase drag for instance low presure reduces fuel economy for the same reason .This drag could cause the converter clutch to slip more and cause 1870 , More thatn likley the higher tire preasure just took off some of the strain ,The problem still exsist if this is the case , you just bought some time ,

so based on what I described it's definatly my converter clutch going. Will the transgo do anything for me? So what is there for me to do, just buy a new converter?

Well buying a new converter may help and the transgo kit may help , If there no other cause such as worn pump stator busings or input shaft ect , How many miles are on your car ,

There's 64,000 miles on it now, I boguht it with 54,000. I don't know whether I should try to fix this problem, or jsut let it ride till it dies and just get a built transmission. I want to spend the least money possible. I don;t know if even if I install the shift kit i will need to replace the trans soon, and it would just be a waste of money for now.

You could have a tranny issue but you put air in the tires and all is well. It is possible that the low tires had thrown off your tune. Meaning tire height. I have seen weird thing happen with guy's who change tire height or rear end ratio's. This effects your vss and can be corrected with a tune. You can probably have that code cleared and then have the test deleated without any more problems. Vince

Thanks for the help guys,
We'll the symptoms are definetly gone, dunno about the problem. I would love for this to have been my only problem, but with my luck I've learned not to be that optomistic.
With all the issues I've been hearing about the Fuddle converters, I wonder if it is my TC going. However, I did a test and, before I inflated my tires, It never happened when I drove for an extended period of time with the converter locked up 3rd gear, only 4th... Dunno what that means.
My tires were very low, like 18psi, but how much of a change in tire hight should that create?

I see, so is driving in 4th actually bad for the tranny?(unrelated question)
Thanks for the info. I'm not a transmission guru by any means, so I guess my question is, What coarse of action should I take about the problem?

Thats a bit lower than I would think would be good for it ,Converter clutches though I know people do use them that way werent really intended to be locked at low speeds or under throttle , Though I can see the advantage to that driving around with a really high stall ,
