So you are looking for information and specs of the r4 transmission on the web? I hope you like the information and if you have any other questions, leave a question in the comment field at the bottom of the article, and I will answer your questions as soon as possible.
So what is exactly a r4 transmission? The r4 Transmission came in the year of The r4 and the R4 transmission replaced the TH transmission in that year. The TH was a 3 geared transmission without the last overdrive gear. The r4 was a big upgrade with an additional gear Overdrivethe 1st and 2nd gear became longer, and the transmission case itself became a bit longer.
To mention all cars this transmission was fitted in; the list would be very long. A lot of people like the r4 because of its excellent durability. It is also very easy to find replacement parts for this transmission.
Torque Converter Installation Instructions
The r4 transmission was not electronically controlled yet; it was hydraulic pressure controlled with a TV cable which acted as a throttle position sensor to control the gear shifting. The transmission then became electronically controlled instead of the TV cable, with some other changes which I will go through further down in the article.
The transmission was made between It had a case length of The recommended transmission fluid is Dextron VI with a capacity of 11 Quarts. The transmission case had 16 bolts and a transfer case of aluminum.
A lot of you reported that you wondered what the differences are between a k-case and the typical case for the r4 transmission. Most of the GM automatic transmission looks almost identical and are difficult to identify for an untrained eye.Torque Converter to Flexplate Bolts - Starter Install vid 8 - GM Chevy Tahoe Vortec LS Engine
However, there are some ways to determine if you have a r, r4, TH or a 4L60 transmission. The easiest way to identify if you have a r4 is to raise your car and check the bolts around the transfer case. The r4 and the 4L60 transmission uses a bolt pattern of 16 bolts, so if the transmission looks like one of the pictures above and you can see 16 bolts, you most likely have a r4 or a 4L60 transmission.
So how can you know which one of these you have? Well, the r4 uses a TV cable as the speedometer, and the 4L60 is an electronically controlled transmission, so if you see wires coming to the transmission on the rear of the transmission on the passenger side, you have a 4LTorque Converter Installation Instructions.
The number 1 cause of vibration is failure to prepare the crankshaft for installation. Each time the converter is installed without sanding out the crankshaft rust, removing the paint from converter pilot and adding a little grease, the converter may be drawn up crooked with the first bolt. This may cause the converter to run-out and usually ruins the pump bushing.
The 2nd most common complaint on converters is a whine after installation.

This draws the converter hub too far out of the pump drive gear causing the gear to rock. Below is a chart that shows how to measure for proper depth clearances. Please check for proper clearances. This is the distance between the engine block mating surface and the converter mount mating surface on the flywheel or flexplate. Compare the two measurements that you have taken. Pull converter off slightly, then push it on again, rotating it at the same time.
Continue to do this until you feel the converter move inward and stop at proper engagement. Do not proceed further until you have installed the converter properly. If you have any questions, please contact our tech department or consult a trained mechanic for assistance. Measure the depth of mounting pad face A from the mounting flange face. Notice that the right hand that is holding the straight edge is also pushing the converter in toward the transmission. All PATC performance torque converters are manufactured in-house.

Wider Carbon Fiber Clutch.Tightening General Motors manual and automatic transmissions to the engine block requires specific twisting force with a torque wrench. The torque wrench allows the mechanic to tighten the bolts at a specific pressure called pound-feet. Chevrolet small-block engines, produced by General Motors, include theand cubic-inch V8s. The torque specifications for the bellhousing that mounts the transmission to the engine block is 25 ft. The harmonic damper's torque is 60 ft.
The clutch pressure plate is 35 ft. The automatic transmission flexplate must be torqued to 60 ft. The manual transmission's flywheel also must be 60 ft. Torque specifications differ slightly between big-bock and small-block Chevy engines and transmissions. Big-Block engines require 85 ft.
The flexplate, flywheel, clutch pressure and bellhousing require the same torque specifications as the small-block versions. GM transmissions matched with 3. The 2. The cover plate to the transmission is 46 ft.
The transmission to the engine block on all pre cars is 66 ft. Model year and later models require 35 ft.

I want to register an account for free right now! Forum Rules. Hi, there. I would get over having a lumpy idle cam in the engine. Totally useless except for the sound if this is a street use vehicle you want to drive regularly. You will quickly tire of it. The question is whether you want that much weight in the front of a Camaro. I would not. A Chevy Big Block weighs in at around lbs with cast iron heads. That is a lot of weight in the front of The resistance in electrical conductors increases with temperature.
It could be something as simple as a plug wire connection at either the distributor or where the wire is crimped to the plug Fighting the return system, going to take some mods to the trunk space sheetmetal to get to the tank. Remember Me? Results 1 to 7 of 7. Jim Standley. Is this normal? When I install the torque converter to flex plate bolts will it pull ths torque converter out of its correct resting position?
Are there spacers that need to take up this gap or is this normal? Register now for free! Henry Rifle. The bolt lugs shouldn't touch the flexplate.
DON'T use the bolts to pull it on. You probably don't have the pump engaged. Rotate the converter while gently pushing in and it should engage the pump and drop into place. If the pump is engaged, and you still have the gap, you need precision shims to take up the slack.
I think he means he has it all together with the converter all the way back against the inside of the trans. The converter should move easy on the shaft. Yes I have it all together with the converter all the way back against the inside of the trans and it does move easy on the shaft. I thought that the gap was a little to large. I have never seen shims there. When you put it in where was it when it the converter went into the pump??
I'm not sure if it came out of the pump when I moved it forward. I will check this morning. As far as were it was when it went into the pump here again I'm going to check it out this morning. I check to postion of the converter when it was fully postioned in the pump all they way back in the bell housing and then moved it forward to the flex plate and it seens to still be engaged to the pump, but its hard to tell for sure.

This popular General Motors transmission is also prone to leaks around the pan because of distorted mounting bolt holes or the pan becoming warped because of improper installation. Setting the pan bolts to 12 foot-pounds of torque is only recommended after the pan is properly inspected and repaired.
Use a 13 mm socket and ratchet to remove the leaking transmission pan. Capture the fluid in a drain pan. Scrape and wire-brush the gasket mounting surfaces on the transmission housing and transmission pan, then wipe them down with mineral spirits to remove any oil residue. Clean the bottom of the pan as well. Lay the mounting side of the pan on a flat surface, and make sure it is not warped. If it is severely warped, replace the pan. If one edge, or flange, is lightly warped, use a shop hammer to straighten it.
Use a flat, round-headed punch to make sure all the bolt holes are perfectly flat and not distorted or stretched from over-tightening. Apply a light coat of gasket sealer to the pan. Fit the new gasket in place, and allow the gasket to set. Place a flat, heavy object on top of the gasket to securely fix the gasket to the pan. Install the pan, and torque the bolts to 12 foot-pounds. Do not tighten the bolts in a linear fashion. Alternate side-to-side and end-to-end to ensure the pan is drawn into place evenly.

Been drving it for a couple months, No complaints. Gonna order the external clutch lock-up kit next since the factory wiring harness is in poor shape. Dropped it in an 85 suburban k with a R4. This truck is a beast like to share photos put the sskit in my 4x4 4l60e chevy pu with a little computer tune it barks 2nd with 38's Thank you.
Excellent converter, very happy with performance, price, and timely shipping. Purchased this converter along with an SS rebuild kit for my supercharged K Works great and the lockup clutch holds tight. I purchased this converter to replace the stock converter during a rebuild of the transmission. The shipping time was great. The fit was also great and work perfectly.
I rate the service and performance 5 star.
