Question about 1998 Lexus Gs 400

1 Answer

Checkengine light is on,very slow off the line,not shifting right

I have a 1998 lexus gs400 that is very clean and taken care of like a baby(only 84,000),but I do have a K&N FIPK. air intake and a pair of borla can's for some growl. my check engine light is on and I do know that the K&N will trip my mass iar flow sensor, but I feel that my transmission is not shifting the correct way. It is very slow in 1st gear. and there is another problem...When you shift or switch the manual/tiptronic mode it just flashes''M''. If there is anyone out there please help me solve this problem. Thank you,Matty

    Hello friend, I fnnally got my car fixed and I also found what the problem was. the place was called the toyhouse in tampa Fl. The mechanic found that my shift selonoid#3(code-p0763) it was stuck and gunked up. What he did was put the selonoid in a bubbler bath of kerosene and it cleaned.Now he used the term "the bubbler". It is a device that cleans out gummed up parts. As I understand he removed the tranny pan.That will you to lose transmission fluid,but you must refill the 4 quarts or so ..Make sure that your mechanic uses a tranny. fluid conditioner when he refills your pan- (BG is a good product for that),but $350 installed is not bad; and tell him that you want the old part if he replaces it or ask him if he can clean it before he replaces it. I know that it can be done if it is gummed up. It could save you $100 bucks. Good luck,Matty

I have the exact same problem. Does it hesitate of the start and then take off? I put an OBD II scanner on mine and it is saying that it is the 1st gear shift cellinoid. Cost's about $350 installed.
