Transmission Woes

Metz Motorsports · April 10, 2005

A friend of mine has a '94 1/2 ton truck. Him and I were gonna grudge match last night at the local dragstrip (no clocks, just heads up). Of course he wanted to do a burnout, the whole 9 yards....anyway....as he 'launches' the truck it accellerates fine, and then all of the sudden its like it went from 1st to OD and was a slug, next thing he knew it acted like it was in neutral. We get it back to the pits where I discover its in 2nd gear, even when the selector is in any foward position. We let the truck sit for about 5-10 minutes, then it shifted fine.

I guess my question is (after all this blabbering) do these trucks have a tranny limp mode if abuse or overheating occurs? I have heard of the NBS trucks having something like this, but wasnt sure about an older one. If anyone has any info about this situation it would be greatly appriciated.

Not to my knowledge, if you cook it you cook it and you should always run a aux tranny cooler on a SUV. When you power brake the heat builds up FAST!!!

The oil got so hot the it did not function for a while and it may have boiled too and got air in system from this if it works now. Change fluid and filter and ad a aux cooler and watch it as it is a sign of trouble.
