The 4L80E was heavily based on the TH400 first produced in October 1963, adding electronic controls and an overdriven fourth gear. The 4L80E's were optioned only in Chevrolet\/GMC pickups, 2500 Suburbans, vans, and commercial vehicles, and the Hummer H1. The 4L80E proved to be a big hit in 1991 with its release in the Silverado 454SS.\u003c\/p\u003e\r\n\u003cp\u003eThe 4L80E (RPO MT1) is rated to handle engines with up to 440 ft lb while the big brother the 4L85E (RPO MN8) is rated to handle vehicles with up to 690 ft lb.\u003c\/p\u003e\r\n\u003cp\u003eThis is a complete 4L80E super rebuild kit containing Alto Red Eagle clutches with upgraded power clutch pack that includes additional clutches and steels.

Imbalance of torque converter clutch apply oil through the front stator support bushing contributes to this complaint. A journal clearance of .002\" or more will generate sufficient leakage to cause lockup clutch slippage, causing the transmission to stay in third gear. Sonnax front stator support bushing 34016-W is designed to reduce leakage by minimizing journal clearance and also increasing journal length.\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan style=\"font-size: 12pt;\"\u003e\u003cstrong\u003eSealing Things Up\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\r\n\u003cp\u003eSunCoast always upgrades the check balls in all of our new 4L80E and 4L85E transmission rebuilds.

The imidized plastic balls seal better than steel balls because they conform to the separator plate ball seats. Steel checkballs are hard and heavy, wearing separator plate ball seats from the repeated high impact of the ball on the seat. Elastomer or rubber check balls seal well. However, the elastomer material wears, reducing the size of the ball. Similar imidized plastic balls have been used on some original equipment late model valve bodies with excellent results.

The 4L80E's were optioned only in Chevrolet\/GMC pickups, 2500 Suburbans, vans, and commercial vehicles, and the Hummer H1.

This item is highly recommended for higher horsepower applications, including sled pulling, drag racing, as well as heavy duty towing (to accept billet P2 hub, machine work required on the P1 sun gear).\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e4140 Billet steel\u003c\/li\u003e\r\n\u003cli\u003eInduction heat treated\u003c\/li\u003e\r\n\u003cli\u003eThis does not include a C2 clutch hub Planetary core deposit ($800.00) is required if pre-shipped (planet must be build able to receive core deposit back)\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"SunCoast Converters","offers":[{"title":"Default Title","offer_id":57273836568949,"sku":"A1-P2K-6","price":925.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0931\/7656\/2037\/files\/F198642618.jpg?v=1780953816"},{"product_id":"allison-shallow-filter-w-spin-on-37711-12","title":"ALLISON SHALLOW FILTER W SPIN ON","description":"\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eALLISON SHALLOW FILTER W SPIN ON\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"SunCoast Converters","offers":[{"title":"Default Title","offer_id":57273836896629,"sku":"37711-12","price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0931\/7656\/2037\/files\/F198642558_f808fdac-20a4-4726-9783-64706d9de5e3.jpg?v=1780953818"},{"product_id":"allison-deep-w-loc-and-spin-on-37710-12l","title":"ALLISON DEEP W\/LOC AND SPIN ON","description":"\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eALLISON DEEP W\/LOC AND SPIN ON\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"SunCoast Converters","offers":[{"title":"Default Title","offer_id":57273836962165,"sku":"37710-12L","price":65.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0931\/7656\/2037\/files\/F198642557.jpg?v=1780953818"},{"product_id":"pinless-accumulator-piston-kit-sc-77998-03k","title":"Pinless Accumulator Piston Kit","description":"\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePinless Accumulator Piston Kit\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eIn listed GM units it is common to have poor shift quality, burnt bands or clutches due to accumulator piston wear. Repeated reciprocation of the accumulator piston causes wear at the piston pin bore interface. After this wear reaches a critical point, fluid loss through the piston pin bore cannot be compensated due to lack of pump volume. In addition, the piston can get cocked and gall the accumulator bore due to the pin bore wear or the spring bottoming out.

The 4L80E's were optioned only in Chevrolet\/GMC pickups, 2500 Suburbans, vans, and commercial vehicles, and the Hummer H1.

A journal clearance of .002\" or more will generate sufficient leakage to cause lockup clutch slippage, causing the transmission to stay in third gear.

However, the elastomer material wears, reducing the size of the ball. Similar imidized plastic balls have been used on some original equipment late model valve bodies with excellent results.

This causes a loss of fluid, resulting in delayed engagement, slips, burnt clutches and\/or bands. Repeated reciprocation of the accumulator piston causes the piston pin bore to wear, while fluid loss through the piston pin bore or cracks causes forward clutch to slip.
