Some transmissions that were done here lately.
This is the start of a performance minded shop for myself. I love to build anything. Engines, transmissions, differentials and axles, to standard repairs.
Some transmissions that were done here lately.
Up and running!
Yanmar 3GM30F for a sailboat going together.
East Coast Performance Powertrains
When you want to wire up TCC Lockup in your 700r4 for pennies versus a 100 dollar kit. I also may find a way to run the relay ground through the brake light switch in order to disengage lockup while hitting the brakes as well. I'll have to do some research first.

Coming along nicely. Looks wonderful!
700r4 work getting started! Might as well be a 4l60e input drum lol everything in it is from a 60e including the molded Hi-per Blue pistons.
Oil pan, water pump, harmonic balancer, coolant temp sender, and spark plugs got installed last night. Nothing much. Time for my 700r4 though👌
Got the valve train in, and adjusted lifter preload to a depth of .035". Lubed the valve train components with a healthy amount of Comp Cams Valve Train Assembly Spray. I had to mock it up just to see what it is gonna look like. And I must say, the attention to detail is working out perfectly. She may not be the most powerful unit, but she's definitely one of the prettiest.
Put in some work today. Measured push rod length. Installed the cam cover and set camshaft endplay. Soaked my lifters in a mixture of 15w-40 Mobil Delvac and high ZDDP STP Oil Treatment. Installed lifters. Installed heads after re-lubricating the cylinder walls. Mocked everything up to see what it would look like, and ensured the top of the intake manifold runners matched the cylinder head runners, etc....
Some new components and ensuring the cam that I installed is exactly what they say it is. The only difference I found is instead of .350 lobe lift, it was .344.
Installed all 8 rods and pistons with my gapped and prepped rings. Everything is going along smoothly. I did however, choose the greatest color combination ever. It looks amazing.
Coming along. Checked all oil clearances, inspected hydraulic roller lifters for defects, finished gapping the top rings specifically to each cylinder, and prepping them for installation by removing any sharp edges that could scar the cylinder walls.
Got the short block back from the best of the best, George Coleman @ CAMS Racing Engines. He didn't mention having to touch up my rod and piston balancing so that must've been done pretty good. He's in the process of reworking my brand new cylinder heads, since FloTek decided they weren't going to fix the valve job, but I'll have some nice pieces when he's done. Lesson, don't buy cheap heads. 355 SBC is finally coming together.
Coming along on the TH350. Converted from a long shaft to a short shaft. All bushings, thrust washers, and thrust bearings are being replaced. New sprags, standard low/reverse clutches, etc... Still waiting for my shift kit to arrive. Out in no man's land apparently. Modified the input drum to increase the cooling and lubrication of the direct clutches. Reman pump that was purchased, due to damaged housing on the original pump, was disassembled, inspected, lubricated properly, and re-assembled. New HEG forward clutches were installed and clearance was well within specification at .030".
350 teardown and block prep is complete.
Finished up the Ford AOD-E/4R70W today. Been a fun one.
Christmas in August
Another one in line. AOD-E. Will be tearing it apart here shortly. Pump stator shaft is broken, and the converter was destroyed internally. Let's see what's on the inside.
Doing some rod balancing. Finished up this set with the small end at 149.5 grams each, and after balancing the big end of each to balance all rods out at 528 grams. Re-checked the piston balance to make sure they were accurate since my cheapo scale was a little off. The new scale I purchased, read them a gram lighter, all within .1 gram.
My first 4l60e rebuild turned out great thanks to Gunther Mizen at Save-Half GM Transmission Service! Nice smooth and quick 1-2, 2-3, 3-4 shifts. 3-2 downshift is nice and quick. Downshifting to 3, 2, and 1 all hold and create nice engine braking, and the torque converter clutch averages a 3 rpm slip at 90% duty cycle. Transmission temperature averaged 183 degrees Fahrenheit which is normal for a radiator integrated transmission cooler. 10oz of LubeGuard Platinum ATF protectant was also installed in with the ATF.
4l60e installation. Didn't get any photos with the transfer case and all that installed.
Just some photos of the 4l60e rebuild that's going on. Had some newbie hiccups, but I'm definitely learning a lot. Transmission had no reverse and upon teardown, found that the hub had sheared from the stock sunshell. The transmission is going together with Raybestos clutches, new updated Borg Warner Low/Reverse Roller Clutch, full new thrust washer and thrust bearing kits, all new bushings, new hardened sunshell, corvette style 95-1 Servo kit, all new solenoids except for EPC force motor, and TCC solenoid. Transmission is also receiving a Transgo 74165 Shift Correction kit, with some special tailoring thanks to Gunther Mizen @ Save-Half GM Transmission Service.
New radiator installed in the camaro and fuel rails and engine cover installed. Also started to mock up the surge tank for the supercharger.
One thing I love about doing these myself, is that instead of a standard +/- .5 gram performance balance, I'm taking the time to get them to within the tenth of a gram of each other. Lightest piston weighed in at 599.2 grams, and the lightest wrist pin weighed in at 144.2. Giving a combined piston weight of 743.4 grams. Got all the pistons at 599.2 and all wrist pins at 144.2 so far.
Static balancing of the pistons and rods now.
Better than it was, by far.
Not to shabby so far. I'm going to sweep up the aluminum shavings and send it back to Edelbrock so they can make a second intake. It appears there will be enough left over haha
Making some rough cuts just to remove excess metal to make the intake match the intake ports and gaskets on the cylinder heads and raise the ports to ease the flow through the port. Will clean em up further with stones and sanding wheels later.
700r4 is now complete. We'll see how it runs when it gets put in.
