'92 Es Rough Shifts In Certain Situations

[myesismybaby]

I have a '92 ES that I just bought from a private party with 110k. It needs work like gaskets in the engine (rear valve cover dripping on exhaust causing smell), new remote keys ($390 from Lexus including new chip for Keyless System), two CV joints, and possibly something transmission related.

When I accelerate then let off the gas before it shifts to second gear (usually in a parking lot or something) or any other time it shifts without being asked for power it shifts with a clunk. When I jump on it and accelerate hard the shifts are perfect. Also, when I take my foot on and off the accelerator on the freeway or at about 40mph or higher I feel a clunk as a give it gas or remove my foot. Why would I feel a clunk only when I'm not requesting power from the car or when I'm accelerating/decelerating on the freeway???

Also, is there any cheaper way to get new remote keys besides going through the dealership?

might want to check your engine mounts

but mroe than likely you are at the beggingin of a clogged valve body

get an external tranny filter and you may just never have a problem again after a few weeks of usage

Will having my tranny power flushed/filter changed be a good thing to do?

always is a good thing especially every 30k miles with the ES tranny
