Default 2002 Lexus Rx300 Check Engine Code Issues

I have a 2002 Lexus Rx300. About 3 weeks ago the car started having issues within the transmission. I took it to the shop and they told me it's solenoid d at fault. But to replace the whole transmission and being female I feel I'm always being pushed to limits it don't need to go. And I can't afford that right now. I replaced the solenoid on the tranny, fixed that issue based on how it drove. Got it on the highway and the rpms are at 3 to 3.5 on the highway at 60 mph. The check engine finally came back on for the same solenoid I just replaced. P0765 and a new code for p1153. I've just put 700 into the car and now the same issues. Any suggestions? I'm thinking it's probably electrical at this point but unsure. Any help is appreciated, thank you

Food for thought ... Do you think if a male family member or male friend would have gotten a different response?

Typically the error codes point to a system which is not functioning right and the tech is supposed to verify the diagnosis by checking if the solenoid is responding to the command or not. There can be an electrical problem [signal to the solenoid] or even a mechanical problem ... when the solenoid is activated does the fluid flow through the channel.

I think we are at the mercy of the mechanic and what we control is engaging a competent and "honest" [broader term] mechanic. One of the equalizer is going to the dealership, where they will charge you more but there will be no gender bias [at least this is what I hope].

My 2c ... Go to a reputable transmission shop and then take their advice.

The P1153 doesn't seem to be related to the P0765, but the diagnostic does say fix other codes first.

The P0765 says the S4 solenoid could be stuck open or closed, but it also says the valve body could be blocked up or stuck. What did the shop say about it?

What do you know about this shop?
Why did you choose the shop?
Is it a transmission specialty shop?
Is it a chain transmission shop?
Did you discuss the diagnosis with anyone outside of the shop after getting the initial diagnosis?
Have you spoken with the shop about what is happening now?
Believe me, being a female may play a role, but I've been played a time or two when I was younger (several times if I think back long enough). I've learned to keep an eye out for trustworthy mechanics and shops. I stay away from chains shops when I can. Word of mouth has a lot of merit. AutoZone and places like that oftentimes know of reputable shops and/or individuals that work on cars. I use a Toyota dealer about 25 miles from my house and have built a good relationship with them over the years. They charge a premium, but I trust their work and advice. This is not to say that they are infallible. They make mistakes and have misdiagnosed an issue on one occasion, but so have I. Transmission issues are difficult in that you are often at the mercy of someone else. A quick fluid and filter change often does wonders, but anything past that often requires a professional.
