Default 1992 LS 400 Transmission

Hey guys, my Lexus is slipping out of gear or not engaging when you go from P to D, I also notice that when I pull up my drive way it also pop out of gear. I think I will need to replace the transmission, but I would like to ask your opinions and what is the usually price range for a transmission. Currently what I done so far is a transmission flush and clean out the filter in the transmission as well. I don’t know if it was a waste of money or not but I did buy transmission fluid at the dealer. It seems that it is getting worst day by day. Any information would be appreciated.

Thank you
J

Seen used trannys on Ebay for as low as $500.00 but your taking a risk. Rebuild would cost from 1500-2500 depending on shop and if they want to replace oil pump as well.

How many miles do you have on the transmission? Did the slipping start after the flush? How was the transmission fluid like before the flush. I too have a 1992 LS with 200K miles with no service.

I having been looking into this flush vs drain issue and I am as confused as when I first started out.

just had mine serviced, tech said no metal and the cleanest pan he had seen in a 93 with 218000 miles.. Mine did same thing around 180000 but it was just a silinoid . minor repair atleast under 700.00 if my memory serves me right they did not replace screen at the repair still origonal to this day.

(drain) do not flush can badly damage trans because if there is metal or residue in pan that can get stuck in lines and valves and once that happens its all over but the walking drain should not cost more than 140.00 with new gasket but make sure they do not change screen/filter that can change atmosphere in trans which may or may not cause damage, depends on who you ask

Hello,

why should the metal stuck somewhere during flushing and not driving? In most cases the flushing will solve the problem.

Exactly!!! When driving you are constantly flusing anyway. Flushing is better than draining.
Fellows, a flush or a drain is NOT going to fix your tranny problems. A flush is a preventive measure that is designed to keep your car running like it was supposed to, and to extend its life. Don't expect your problems to go away magically. Yes, a flush may make shifting smoother or less noisy, if the tranny fluid has 100k miles on the original fluid, but that's about it.
Also beware, the wrong type of new fluid can cause more harm than good. Make sure the fluid is Type-T-IV compatible.

There is a magnet in the bottom of pan. when you flush they flush it at lot of pressure almost twice the pressure when you are driving Plus its the cleaner they pump in! youre trans has a very important atmosphere.also it will save you money dropping the pan. but to each his own. its just my opinion hope this helps!

well the car did not run when i first got it, like i mention on my first post, i got the car really cheap. i can say that the tranny will cost more then the car. my dad drained the tranny fluid and did clean out a fliter from what he told me. he did not mention any metal flakes anywhere. would the torque convertor be the problem?

joshnoel - what is this silonod that you are talking. i am new to lexus and i do not understand. sorry.

thank you for the input guy

unless you get a junk tranny from ebay (which I am sure most will have problems anyway) for $500+, you are looking at $3,500 for a rebuilt one from a mom and pop shop, or about $6,000 for a rebuilt one from a Lexus dealership.
