I just got my truck back on the road after 8 months out of service due to lack of $$$$,Rebuilt IP new Injectors and a trans rebuilt by a friend.With about 150 mi the trans is slipping real bad.I need my truck real bad and am tired of paying for a dead horse.I found a GM reman 4L80E trans out of a 94 gas truck with about 20K miles.In the local paper this would give me time to figure out what went wrong with mine and give me a back up when mine is fixed or vice a versa.Anyone have any idea if they will interchange?

Thanks.

Any DTC codes?

Look in FAQ's for method of pulling the codes without a scanner.

His is a 98, don't think he can pull codes w/o scanner.

Oops! Yer rite!

Ok - an OBD-II scanner\code reader is available from Harbor Freight for 40 bucks

Just plug it in, and weep!

IIRC the trannys are the same except you need to use your diesel torque converter

94 Trans will not work.

Does anyone have any recommendations for a good affordable reman trans supplier?

 

[quantum mechanic]

No, '94 and '98 have different shift linkage that will have to be switched.

Give Suncoast transmission a call, they are a site sponsor, mostly for DMAX trans, but at dyno day they hosted 2 years ago I was impressed with their shop, I'll bet they know their way around a 4L80 as well.

moving this to the transmission section, you may get better responses there, more than 1 tranny builder on the site
