Transmission delay issues

Hello, I have an 06 4.0 v6 4runner with 4x4. I recently had an issues with my transmission, I'll link to that post.
I had an issue after a neutral safety switch replacement that landed me in the trans shop. When I got it back i had a new issue; When shifting from park to drive there is a 3-7 second delay before the vehicle actually engages into drive. I had two shops look at it and no one know why this is happening. Someone suggested that it could be an internal hydraulic leak and that its taking some time to build pressure to actually engage.
I was quoted $4k for a new used trans or $4k for a rebuild.

Everything still shifts fine, everything else works fine. I bought a truck for work and unfortunately need to sell the 4runner. I'm trying to replace the trans for way less than $4k.

All of that being said, Ive called every junk yard near me and only one of them have a 4runner and its a 2003. The Junk yard is telling me the 03 trans won't work with the 06 but I believe they are in the same generation so i wanted to see if anyone has any insights on how to fix the trans or if I can swap in the 03 trans.

edit* It was quickly answered that the 03 will infact not work, still looking for any advice or suggestions on finding a new trans or suggested fixes/ causes for the delayed issue

Thanks,
Jake

At this point how much are you really saving as is? KBB says its worth around $7k. I would just sell it as is and maybe some mechanic will pick it up for a decent amount.

This is my previous post.

 

Gotchya, thank you!

 

The 03 still used the 4speed auto, while the 06 has the 5 speed.

The 5 speed replaced the 4 speed in 05.

 

Just to clarify, the 2003 and 2004 V6 engines both had the 4 speed, but the 2003 and 2004 V8 engines had the 5 speed, albeit the 2003 V8 5 speed was not a sealed transmission, had a dip stick and use different ATF than the later 5 speed, and as mentioned from 2005 and onward all engines had the sealed 5 speed transmission, the only other difference is if it's a 4X4 or 2WD, it's still the same transmission...BUT the tail piece of the transmissions are different, so if you have a 4X4 you need a transmission from another 4X4, or if 2WD....etc., etc., etc.

 

Awesome, thats great to know! Thank you!

 

Grease your driveshaft mine clunked when going into drive

 

Couldn't agree more. You're never going to get your money back by making a major repair to an older vehicle you're ready to sell. Mechanics and hard core DIY people tend to like projects and probably have the ability to source a used transmission as a replacement or to fix the existing one cheaper than you can. Rather than spending $4K to fix the transmission (which could turn into a mess if the fix doesn't work out well) and asking $8-$9K for the vehicle, I'd disclose the issue and price it at $5K to give the seller some financial room to fix it.

 

Were you able to fix this issue? I have a 2015 4Runner, and have replaced the Neutral Safety Switch and rebuilt the transmission, and the delayed engagement into drive still persists!

 

Have you drained and refilled ATF? Did the shop accidently let some ATF out and now your tranny is low? Does the ATF have odors, like different from new ATF-it could be contaminated or burnt?
What is history of ATF maintenance intervals for this truck? What is color of existing ATF compared to new ATF?

 

Thats the rebuilders problem

 

The delayed engagement from park (or reverse) to drive started when it had less than 85,000 miles. No ATF maintenance had been done. First mechanic thought it was the neutral safety switch, annd replaced it.

Transmission was rebuilt ant 125,000 miles. All seals, O rings and fluids were changed when the transmission was rebuilt. The sun gear shell was broken, which I hear is rare. May sound strange, but if I shift quickly from park (or reverse) into drive, there is no delay in engagement. I get a delay when I don’t shift super fast.

 

I get a slow shift from park to drive, or reverse to park, etc. I figured its some sort of actuator, not necessarily the actual transmission. I could very well be wrong... but its something i feel like i'll have to deal with at some point, just not today.
