I am doing a 65 Buick Special L33 4l60e mod. Do you have a part number for the Griffin dual pass radiator?

1989GTA

The part number for the Griffen radiator is 8-00019-LS.

A little update as to what is going on with my car. As some of you know I have a motor and E38 ECM from a 2007 Escalade. I have found out my 6L80 transmission is out of a 2010 vehicle such as an Escalade, Tahoe, Silverado or some such 2010 model. I am in the process of seeing which operating system is in the 6L80. With any luck I can use the 2010 Camaro E38 program as that is essentially what my motor is now with all the modifications.

I have since purchased HP Tuners and a new laptop just for the car and a backup. The laptop has Windows 8 on it and I am not familiar with it at all and I am having trouble navigating around it. Call it a learning curve. Well the program CD that was sent to me will not load up on the laptop. There is a problem.

Long story short is I got tired of playing with it and took everything over to a local computer store and ask them to upload the program for me. The first store said he will not work on Windows 8 as he has had too many problems. I went to another store and he said Windows 8 has some problems and he has not ran across anyone who likes it. He said he could upload the program for me. But also recommended that I change over to Windows 7 as that is a more stable platform. The price was good so I should be able to pick up the laptop this Saturday and see what program is in the 6L80.

Bottom line for anyone doing this type of conversion is to make sure the TCM and ECM match at least to the year. That would go for any other components such as a BCM

Sorry you're having trouble with it. I'm sure someone either on here or in the hpt forum will be able to point you in the right direction.

1989GTA

Thanks Bandit. Things are progressing though slower than I would like at this point as I have to wait on other people and their schedules. It is all coming together and I just need to get one more piece of information off the 6l80 transmission and then I will kick this thing back into high gear.

what are you doing with Pin 59 YEL/BLK in the black connector for your PCM?

I ended up buying an ECM from PSI and sent my 2010 Escalade TCM to them so John could get them talking to each other. Guess I'll find out how he did when the car is road worthy, fingers crossed.

1989GTA

If you mean Pin 57 yel/blk I ran it to my speedometer. I don't know if that works yet. The car has only been driven a very short distance. If the speedometer does not work I will purchase the new Speedhut version that works off the GMLAN signal. It is around $200.

Sorry maybe pin 59 is just yellow. I should have clarified why I asked. The PCM stays awake for a few seconds after IGN+ is shut off. The TCM doesn't. If you have your TCM IGN wire bundled in with the rest of the IGN wires, the TCM will shut off immediately with the ignition switch, while the PCM stays awake for a brief period. If the PCM can't comunitcate with the TCM during this brief IGN off awake period, it will throw a code. Not sure if that's your problem here, but it might be worth looking into.

Pin 59 is used to control a "powertrain control relay" from the factory. It stays powered during that sleep period. Use it to power the TCM IGN+ circuit, either directly or via a relay.

I am using the factory harness and have followed the factory wiring diagram to a "T" except for those items I am not using such as the rear O2 sensors.

I think I finally have the best solution at hand after quite abit of research. Here is the latest plan. Going to remove the T43 TCM out of the 6L80. I have already purchased a new E38 ECM with service number 12633238. I will ship both off to Speartech and have the 2011 Covette program downloaded into both. This is the latest and greatest program from GM that will work with what I have.

I did not know this but you can activate VVT with the Corvette program or at least John at Speartech knows how to load it in. Once I receive all this back from Speartech I will send the ECM off to Texas Speed and Performance and have them down load all the ignition curves, fuel tables and what else into the ECM to match the modifications I have done such as the cam, headers and exhaust. Hopefully at this point I should be able to turn the key and car should run pretty good.

I will probably take the car out to Westech in Mira Loma, California for the fine tuning and the dyno tuning. I am really happy with this solution as it matches the componets I have bought for the car. Car will be going back into the shop Thursday for the TCM removal out of the 6L80.

Another update on the project. Got the new rear springs installed to raise the car up a little in the back. Sent the transmission control module and the E38 ECM off to Speartech to have them reprogrammed to the 2011 Corvette configuration. Received them back and sent the E38 off to Texas Speed to have all their tables downloaded into it. Should arrive back on Monday.

Hopefully the car should run half way decent. We removed the front and rear bumpers in preparation for sending the car to the paint shop. The car has not been out on the road and I assume the car will settle down some in the back when that does occur. Here are some photos.

The car looks great! Did you ever change out your tranny pan? I'm looking a swapping one from a 2006 Caddy STSV and was just curious.

1989GTA

No I have not. I am seriously thinking about going to the G8 6L80 pan. Looking under the car the trans oil pan is by far the lowest thing. It has just under 4" of ground clearance. The G8 pan supposedly would give me another 3/4". Is the Caddy pan shorter than the truck pan?

Yes. I still haven't installed it yet, but here are a couple of pictures of both pans.

1989GTA

Hmmm, that looks good. I am going to do some research on the Caddy pan. Thank you for posting the pictures.

Cutlass Convert

I bought a shallow G8 pan but then really struggled to find a shallow filter to work with it. All the G8 filters I came accross were for the deeper truck/camaro/cts pans.

I ended up discovering the 11-13 Chevy Caprice pan was shallow and ordered that filter.

Shallow Pan = 24239528 (rock auto says this is for 11-13 Caprice & 08-09 G8 )

Shallow filter = 24252158 (rock auto says this is for 11-13 Caprice)

I bought both of the above from Rock Auto

No problem. I'll post pictures when I get it installed. Here's some pictures of my junk and a link to my build thread. Cheers!

I believe those are the same part numbers I got.

1989GTA

Thanks guys that is good information. I installed the E38 ECM and fired up the car. The good news is the communication problem is gone and now the ECM is talking to the 6L80 TCM. I have two codes, actually three with the fuel pump code but I can delete that with HP Tuners.

The first code is my MAP reads high. I am using the MAP out of the 2007 Escalade so I ordered the newer style MAP expecting the problem but the harness plug does not fit. So I ordered a new pigtail and it should be here tomorrow morning. The 2nd code is a throttle position sensor code. I did not have this before so I might have to swap a couple of wires. I am using a Corvette gas pedal.

Here is a picture of the ground clearance with the stock truck 6L80 oil pan. With the above Impala oil pan maybe I can gain another 1/2" and get it up to around 4.5"

Edit: Nice build on your truck. A very clean installation.
