Transmission Failure and Rebuild 3/18-26/2015

Well... it came back and bit me.

When the motor was being rebuilt, the transmission was out and I was going to take it to the transmission shop to have it inspected. Since I could not get to the shop in time (work and school), I just had the shop change out seals and gaskets. I was also told tranny was good.

Well, after some basic research, I found out the S/C previas had the same transmission as the supras, which means they were beefier transmissions. So I had a false sense of "it should be okay".

WRONG.

A weeks ago, there was a noticeable long delay going into the lower gears. Then it got progressively worst with a sudden hard shift in to 2 and 3 gear. I had about enough of it.

I took it to the shop that did my motor (and it has been a few months) and they said it feels like the clutch packs in the first couple gears is going out and that maybe the internals are damaged.

I thought about it and took it to a transmission shop (the one I originally wanted to take my transmission to when the motor was out) for their opinion. He said the same issue after a test drive. I asked him how long it would take, he said if he took it that evening (Thursday) it won't be ready til Tuesday.

NOW -  I could either get another transmission (as I've seen at junkyards and craigslist) to save money in the short term, but what is gonna happen long term? The mentality of Replace vs Rebuild came into mind.

As I contemplated this idea, I called my wife and give her my idea. She said financially, it was okay to get it done. I was happy and had no hesitations calling the transmission shop after. I dropped it off and asked for a shift kit as well.
----------------------------------------------------




Well, the transmission was completed, but they asked about the transmission mounts because they were old and ripped. I gave the okay to order the mounts, but it was going to take 3 days.


I paid the for the rebuild, which was under what he quoted and $600 cheaper than the shop that rebuilt my motor quoted me.

He showed me the forward drum where the clutches were burning and falling apart and explained why going in the low gears was going out.

-------------------------------------

As anyone normally would do, I got on it and just to check the shifting... and WOW, it moved like a car!!!

Got on the freeway and stepped on it...

This transmission felt better than any previa I have driven. That shift kit made a difference.

Once the transmission mounts come in, I will probably look at mounting a transmission cooler.

EGR system Clean out and Code P0401

EGR system clean and Code P0401 This is another MUST DO on the previas, especially if you are having issues and code P0401 being thrown. P0401 is "Exhaust Gas Recirculation flow insufficient detected".  Parts: - EGR intake gasket - 25628-76010 - this is on the far right side next to the exhaust. - EGR valve gasket - 25627-76010 - used for the EGR valve to the intake manifold.  -Air inlet duct gasket - 22273-76010 - this is where the air goes into the intake manifold and where   the EGR port gets plugged. 1 container of coolant I did buy a set of crow's feet and Universal joints for the Exhaust pipe. I followed Zenseeker's photo's on every single detail. If you haven't visit his website (http://zenseeker.net/Previa/PreviaMaintenance.htm), it is a treasure trove of information!!!  Zenseeker gets the credit and this would have been impossible for me to do without those pictures! **The pictures are located at the bottom of this po...

I GOT A COOLBOX!!!!!!!!!!!!!!

I found out that the previa had a "cool box", which is like tiny fridge under the dash in the middle, from Toyotavantech. I have seen them only in photos and in Canadian spec previas (unsure if they were in US spec). Even our owner's manual has some mention of them. Often times, I would look at CL in Vancouver BC in hopes someone wants to sell or part a van with it. Now, I've seen a few different versions, in which I don't have the ones that are pictured below. (note, these cool box images were found on the internet). A slanted shape one  This is a cool and hot box, 3 buttons on top ------------------------------------------------------------- I've kinda looked at the cool box as a Holy Grail. 9/12/15, Saturday. After volunteering my morning at the farmer's market making boxes and putting fruits and vegetables for low income families (Phat Beets Produce!) here in Oakland, I went to go fill up gas in ...

Comparison of the Estima (ACR), Estima Aeras (TCR) and Estima Emina..

I'm here in Vancouver BC and stopped by a shop called Velocity Cars. It is a car lot that sells some imported Japanese vehicles. Import laws are different in Canada. These are all legal. They had 5 Estimas. 2 ACR Estimas, 2 TCR Estimas (like the US previa) and One Estima Emina. Looked at all of them to see their differences. They are all 8 seaters as well. First I looked at the Estimas (TCR) that were the same body as the US Previa. Besides the awesome upgrades, one was lowered, but they are the kouki versions, so newer headlights, tail lights and one had the newer Aeras roof rack. Both were AWD. The side mirrors' top were extended like a sun guard. Obvious difference in the outside, but the inside, pretty much the same. There were some small differences. 1. Rear A/C had more buttons for adjusting flow. 2. The lower tray. US previas had a tray (some didn't). Of course some Canadian models had the cool box set up. The Estima has a tray, but it is raised. The to...
