700R4 Shift Kit 1982-93, new and ready to install. Fits the 700R4. Ships fast from the USA.
A cable-controlled 700R4 that flares into third, bumps on the 1-2, drops out of overdrive, or has already eaten one 3-4 clutch pack is usually telling you about its throttle valve system. This is a new TransGo SK700 shift kit for the GM 700R4 (renamed 4L60 late in its run), covering the full 1982-93 production span found in Chevrolet and GMC C/K pickups, Blazers, Suburbans, Camaros, Corvettes and Caprices. It is a valve body repair kit: springs, valves, check balls, seals and gaskets that recalibrate how hard and how fast the transmission applies its clutches and band.
The 700R4 has no shift solenoids and no computer setting line pressure. A throttle valve (TV) cable from the carburetor or throttle body strokes the TV valve in the valve body, and that TV signal raises line pressure as you open the throttle while the governor and TV oil together decide shift timing. When the TV valve sticks or the cable reads short, the unit runs low pressure under load, and the 2-4 band and 3-4 clutch slip on every shift until they burn. The SK700 replaces the factory TV parts with TransGo's Bootstrap TV system and a No Stick TV valve, then recalibrates the pressure regulator spring, the 1-2 and 3-4 accumulators, governor springs and several shift valve springs so the rest of the valve body works with the new TV curve.
Rule out the simple things first. Check the fluid level and condition: dark, burnt-smelling fluid with friction material in the pan means the clutches are already damaged and the kit should go in with a rebuild, not instead of one. Next, verify the TV cable reaches full travel at wide-open throttle and returns freely, because a binding cable or bracket will defeat any kit. If the 1-2 and 2-3 shifts are harsh or banging rather than soft, read our 700R4 harsh shift causes guide before buying parts. For a unit that never reaches overdrive or drops out of it, the 700R4 won't shift into overdrive guide separates a 3-4 clutch failure from a governor or TV problem. A worn pump-side TV boost valve bore is another cause of low line pressure that a valve body kit alone will not fix, so a line pressure gauge reading is worth taking.
This kit fits GM 700R4 and 4L60 transmissions from 1982 through 1993. TransGo designed it around the early type-1 valve body used from 1982 to 1987, and it also fits the type-2 valve body introduced for 1988, so it covers every year in this range. On 1983-87 valve bodies the kit includes a provision to make converter lockup work without wiring. It does not fit the electronically controlled 4L60E; if your case has a wiring connector and no TV cable, compare the two with our 4L60E vs 700R4 identification guide. If you are unsure which valve body or transmission you have, send us the year, vehicle and VIN before ordering. Every other part we stock for this family is on the 700R4 parts page.
The SK700 can be installed with the transmission in the vehicle by dropping the pan and removing the valve body, or on the bench during an overhaul. Work one valve bore at a time, lay removed springs out in order and compare each against the kit's color-coded replacement, and note every check ball location before lifting the separator plate. The kit supplies new valve body gaskets, accumulator seals, orifice cup plugs, a .076 inch drill bit and a roll pin extractor, plus a servo cushion spring and shim for band adjustment. If the clutches or band are worn, install it alongside a 700R4 master rebuild kit, and if the valve body bores are badly worn, a replacement 1982-1987 700R4 valve body may be the better base. Refill with DEXRON VI or an ACDelco Type III (H) fluid, adjust the TV cable to specification, and road test for clean light-throttle and full-throttle shifts before regular use.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. TransGo built the SK700 around the 1982-1987 type-1 valve body, but it fits all 1982-93 700R4 and 4L60 valve body types, including the type-2 body used from 1988.
Yes. The kit installs with the transmission in the vehicle by removing the pan and valve body. If the clutches or band are already burned, though, it belongs inside a rebuild.
No. This kit is only for the cable-controlled 700R4 and 4L60 through 1993. The 4L60E has an electronically controlled valve body and needs its own kit.
The kit includes new valve body gaskets, valves, springs, check balls and seals. Reuse your original separator plate unless it is damaged; a replacement plate is a separate part.
GM's current recommendation for older units originally specified for DEXRON, DEXRON II or DEXRON III is DEXRON VI or ACDelco ATF Type III (H). Adjust the TV cable after the refill.
Yes. The Bootstrap TV system makes the transmission more tolerant of cable error and stops a sticking TV valve, but the cable must still be set correctly and confirmed on a road test.
