Thanks sk .. will do that .. I just found an excellent NON STARTING DIAGNOSTIC CHART .. Im going to try to attach it. thanks again. Hope this chart is Helpfull to others. Ken

QUICK QUESTION AND I HOPE I GET A QUICK RESOLVE. BEFORE DOING EXTENSIVE READING , IM HOPEING SOMBODY CAN PIN POINT THIS PROBLEM REALLY QUICK. I JUST GOT HOME FROM HAVING MY CAR TOWED 39 MILES. PROBLEM WAS THIS.. WENT TO COURT.. (BAD THING IN THE FIRST PLACE ) CAME OUT AND THE CAR WOULD JUST TURN OVER AND NOT START. LIKE IT HAD NO SPARK OR SOMTHING .. CHECKED FUSES AND DID WHAT I COULD WITH NO TOOLS. DRIVE 39 MILES IN A TOW TRUCK WITH TWO SWEATY GUYS.. TAKE THE CAR OFF THE TRUCK, AND PUT THE CAR IN THE DRIVE WAY, TURNED THE KEY AND IT STARTED. AFTER HOURS OF NOT STARTING AND CHEKING THINGS. IT JUST ALL OF A SUDDEN STARTED AGAIN. SAME THING HAPPEN LAST WEEK BUT STARTED WITHIN 2 MIN. ANY BODY HAVE ANY IDEAS ? COIL ? FUSE ? ALL THE FUSES UNDER THE HOOD WERE GOOD. EFI ECT. IS THERE SOME KIND OF OIL SWITCH THAT WOULD PREVENT THE CAR FROM GETTING SPARK ? IM CURIOUS. THANKS .. FLORIDAKEN 1993 SC400 245.000 MILES .. TIMEING BELT ALREADY CHANGED.

did you ever think that the tranny mounts were the cause fo the hard shifting?:whistles: :) i had to say something. LOL, but at 250K, you can pretty much rest assured that the tranny you are gettig has fewer miles. i woudl keep the old one just in case. BTW, when you enlarge the pix you put up...they dont work. ← dam shame about the pics.. wonder why ? any way , yeah I thought about the mounts and the hard shifts, but they had nothing to do with this kind of hard shift.. it was like a shift kit but harder , was like sombody running into the back of the car whehn it hit over drive. any way.. new tranny is in , and its smooth. drive shaft needs u joint, other than that, its really nice.. put new mounts in too . tell ya what.. what an education you get about (tv, drive shaft, tourque converters, electrical on the tranny) when you change one out for the first time. oh yeah.. I still have the other tranny.

Oldest parts dealer ? Bennette ? email me k ? Ken

hey Lex, I can buy on line and change them later, mean time Im thinking gorella glue lol or jbweld for the old mount, the rubber is just seperated from the metal on the mount, the rubber on the mounts look brand new, except for the seperation.. If its not to pricey I guess I could buy them at toyota.. I will check it today, if you have some sorces i would like to hear about them. time into the tranny drop? I have close to 16 hours on my back (asphalt) under that car It took a long while cuz i was gun shy and its the first lexus ive had , got as much info from here and clublexus as i could, printed all diagrams from alldata.com and from a chilton IMPORT CAR REPAIR MANUAL 1993--1997 . I was suprised at the info and diagrams that manual had in it, $39.00 at pepboys. Also, I have the 92 lexus sc400 cd from ebay, If you give me your email addy, I will send you all the pdf files from it.. (if thats ok with sys ops here on the forum of course) Listen, a lift would have been wonderful and air tools even better, I pulled a lat muscle (left side back) breaking those bolts from the tranny without the use of my legs and glutes.. lol.. any way ,, another lesson learned. Hey, found somthing interesting, look at this. toyota corola, with a lexus v8 in it, check this link out. http://www.clublexus.com/forums/showthread...190#post1215190 This same guy, has built twin turbos for the sc400, took them off of a mr2. here is his post............ 2 toyota ct26 turbos from mr2s..they are more of a medium sized ct26, and have a twin entry--the exhaust housing is split/divided in order to keep velocity high.. theat keeps the potential hp down, but makes for quick spool and great street turbo-bility?.. toyota also has larger turbos from early supras that have more potential hp.. all of these turbos can be had for cheap on ebay.. this car also has 3 inch dual exhaust all the way back from the 3 inch down pipes.. it is driven everyday,, and so far has proved reliable..the only mod to th engine has been a fuel press regulator.. it has been dynoed at 370 rwhp at 8psi.. and has run a 13.7 at about 109 mph at the track.. the car/ engine has about 150,000 miles on it.. hope you find it interesting thanks for the help. ←

Hey Lex92 , thanks for the reply , Im using jack stands , five of them , I dont have a tranny lift. I just took the exaust out today and am to the point of the catalitic converters, what a pain in the !Removed! they are to get at .. have to buy a long 14 mill closed end, will get it tomorrow.. btw , Im thinking of hollowing the cats out.. hinder or help? i did it to my f350 and picked up 1 mpg. any way I have not picked up the used tranny yet , have a deposit on it, but since ive had the car its shifted hard into 4th gear, like sombody hit the back of the car with a hammer, every time.. so im thinking the used tranny will be a better thing to do, and I will always have the spare tranny to educate myself with. I need new tranny mounts too there not holding anything at all.. found that out today also. is the bushing between the tranny and the propeller shaft supposed to be out of round.. ? I wouldnt think so but it looks like it is. and I have a 1/2 inch of play in the diff, when i turn the drive shaft. any way ,, tranny will be out tomorrow. thanks ← I just picked up a used tranny from the bone yard. it looks alot better than the one i took out. noticed the sleave on the old torque converter is scorn with groves in it, and it looks like the seal that held the converter sleeve is bad on t he old tranny, now the new(used) tranny looks great, I have inspected the ring gear, dosnt seem to be any cracks in it and the teeth look great. not gonna change that ,, but the hole where the shaft of the torque converter is like 1 5/8 of an inch in diameter , it had me looking for a pilot bearing, I dont (hope) think that it had a pilot bearing ,, one didnt fall out when i took the old one off... well .. tomorrow the tranny starts going back in , just swapped all fittings from old tranny to new.. oh .. I need a transmission mount , both of these are bad ,, any sorces for that besides lexus?

guys, check the forums . there is alot of info with all specs on this. do a search, just a suggestion . archives

Well Im sure I have all the bolts out that mount the tranny to the engine, have to check the starter though , I didnt think that had to come out on the sc400, but I will check it. Thank you for the information , I will let ya know later how it went , on my way there now

where did you get the tranny ? and who did you have install it ? Ken

looks like it turned out to be a combo of things. mass air flow, ISC, vacume lines from poersteering pump. Thank you for your help.. Ken

yeah buddy ,, I changed it.. ohmed it out and it was bad,, so got another one ,, its within range.. but that wasnt the problem.. (even though my other didnt ohm out right, so it needed to be changed) Thanks for the Information and all your help. Ken

Yes I did and guess what ? they had leaks in them, they were part of the problem.. Thank you for your information, it was greatly appriciated. Ken

1993 lexus SC400 Ya Know Im Just in the mood for some self abuse :chairshot: , So now I am going to try to take my tranny out and put a bone yard tranny in , I just got off of the saw grass, and If I went back there you would still see where I was from the smoke my tranny fluid left , burning off of the exahst system .. seems as soon as I put tranny fluid in , it runs out between the motor and tranny, Might be a seal , but I dont want to get into that, car has 250.000.00 :o on it and I am going to take a chance on a bone yard tranny.. my question is this.. has anybody done this recently and if so, Any Things I should pay close attention too or any warnings about taken this out and replaceing? going to do a tranny and torque converter, maybe even play with the cat converters while I have them down. (hollow them out) any other suggestions would be appriciated. BTW, when i looked under the car, a stream of fluid was leaking from(what looked like a weep hole) between the motor and tranny housing, a seal ? Ken B)

yeah? 700 bucks too huh ? any Idea where its located ?
