About the 700r4 & Common Problems

700r4_transmission

The GM 700r4 is a 4-speed automatic transmission with overdrive. It was introduced in the early 1980’s, as way to make their V8 powered cars and trucks more efficient. In a world filled with rising gas prices, the General needed to keep its product line relevant.

Adding a 4th overdrive gear allowed them to make their sports cars and pickup trucks more affordable to drive. The 700r4 transmission replaced the 3-speed TH350, and became a popular upgrade for older rear wheel drive GM vehicles.

Broken Input Shaft

Overheating

Another common issue with the 700r4 is overheating. Given the high power output, and extreme use that most vehicles equipped with this transmission see, overheating is fairly easy. As the ATF temperature rises, significant internal damage can start to occur. To avoid this problem, simply install an auxiliary transmission cooler.

3-4 Clutch Pack Failure

Slipping between 3rd-4th gears can signal a problem with the clutch pack that engages those gears. Overheating can weaken the metal used to make the 700r4 3-4 clutch pack discs. If this happens, the ends can shear off, and you’ll eventually have a serious problem.

Warped Valve Body

Due to overheating, the valve body can become warped, which can significantly hamper gear changes. If this happens, you’ll be on the hook for an expensive repair.

Stuck Governor

700r4 vs 4L60 ā€“ Are they the same?

In 1990, GM changed the name of the 700r4 transmission to 4L60, which stood for 4-speed Longitudinal 6,000 lb gross vehicle weight rating (GVWR). For 1993, the hydraulic shifting system was replaced with electronic controls (4L60E). A Vehicle Speed Sensor told the engine computer how fast the vehicle was going, that way it could decide when to change gears. Shifts were then executed by sending a signal to the appropriate shift solenoid.

I have a 305 tune port fuel injection motor and has a 700R4 automatic transmission and the 305TPI,700R4 has been completely rebuild for street/strip set up in my 86 camaro IROC Z28 and I am curious if I can replace it by taking out the 350 throttle body fuel injection motor and has a 4L60E automatic transmission in my 1995 Chevrolet Silverado ext. cab four wheel drive truck so is it compatible to swap the motors and automatic transmissions

Truck won’t allow transmission to engage until fluid is warm and it has a tendency to stop working . When transmissions cold it won’t go in any hear ? I got the truck doing some wheeling and dealing and was told it had a transmission leak and when the man I got if from brought it to me he drove it to my house ? He told me to change filter and fluid and said it would fix the issues it is having ? The truck sat for a year and leaked out almost all the transmission fluid any opinions on how to fix it because I’m on a really tight budget and don’t have the ability or funds to be able to afford to r replace it’s transmission . Any tips and pointers would be greatly appreciated . Before the man I got it from parked it and allowed the fluids to leak out I was told by him and several of our mutual friends that the transmission ran good And shifted good from gear to hear but I’m trying to get as much help and information as I can to try and get it back to how it was before dude parked it and it started not wanting to even try to go into any gear until transmission warmed up enough to thin down the fluid enough to allow it to penetrate the tranny’s filter once fluids warn it will shift into reverse as well 1st and second usually takes about an hour f
Of warming up before it will do any thing at all please help

I’ve lost reverse and 2nd and 4th gear wanted to know what is the problem exactly but we know that’s never possible with being a member of the mechanics life style cause I was raised by my dad the best in my eyes but i was trying to find out where should I start with this situation

Was driving when vehicle stalled, upon restarting and putting it in gear the Trans is slipping badly but will still move the truck. I’ve changed the filter and fluid. This gave me an actual shift into gears from park that I can feel but only slightly lessened the slipping. It’s an 84 gmc k1500 seirra, and yes the fluid was filthy.
